While Everton did not reach a deal to sign Zaha, Marco Silva still boosted his squad considerably with the likes of Fabian Delph, Alex Iwobi and Moise Kean.
A slow start to the summer transfer window picked up speed in the final few days for Palace, who added Gary Cahill, Victor Camarasa and James McCarthy to their side.
But where will the game be won and lost on Saturday? talkSPORT.com takes a look at three key battles which could have a big say on the final score.

Richarlison vs Patrick Van Aanholt
The Brazilian was Everton’s joint-top scorer in his debut season on Merseyside with 14 strikes and turned in a number of impressive displays.
Coming back from his Copa America success with Brazil, the former Watford man looked impressive in pre-season and gave Werder Bremen’s Marco Friedl plenty of problems with his pace, directness and his ability to drift inside and help down either the left or right flank, which was evident throughout much of 2018/19.
He scored twice on the opening day last season in a 2-2 draw with Wolves and is among the favourites to get among the goals in this clash.
An attacking full-back, Van Aanholt, is likely to be seen playing one-twos with Luka Milivojevic or Max Meyer as he flies down the wing to support the attack.
The Dutchman could be in for a busy afternoon if he is caught too high up the pitch, but he does have the pace to match Richarlison.
Gylfi Sigurdsson vs Luka Milivojevic
Sigurdsson has previously operated as a false nine, second striker and played out wide on the left.
However, his best position is as a central midfielder, where he is able to read the game and act as the orchestra to build Everton’s attacks.
Last season he scored 13 times from midfield and assisted six and is likely to benefit from having a more clinical striker in front of him in the form of Kean, while being flanked by the likes of Bernard and Richarlison.
The loss of Idrissa Gueye to Paris Saint-Germain will massive, such was his tireless role and ability to let the forwards flourish.
While Milivojevic plays in a more defensive role, he is still the reliable platform for which Palace go through in order to build play or steady the ship.
The Serb is both an excellent distributor and his ability to win back possession is often overlooked, with many choosing to focus on his efficiency from 12 yards, where he is probably the Premier League’s best penalty taker.
Gary Cahill vs Dominic Calvert-Lewin
The former England captain played just twice in the top-flight last season, having not been part of Maurizio Sarri’s plans at Chelsea.
What Cahill does bring to the Palace side, is a wealth of experience and his ability to lead in a natural, unassuming manner will be vital to The Eagles, who look a little light in terms of depth this season.
Despite his lack of action, the 33-year-old has maintained his fitness and could make his debut on Saturday.
He will hope to avoid a repeat of the last time he played on the opening day of the season, which was two years ago, when he was shown a red card for a high tackle in the 14th minute, as Chelsea lost 3-2 to Burnley.
Calvert-Lewin is likely to lead the line ahead of Cenk Tosun, with Kean presumably introduced from the bench at some point in the second-half.
While he is fast and energetic, his finishing can leave a lot to be desired and his performance in the final pre-season match did little to suggest he warrants the role at the weekend.

Moise Kean rejected the chance to join Arsenal in favour of Everton due to their reluctance to promise first-team football, according to reports.
The Juventus striker is set to seal a switch to the Merseyside club in a reported £37m deal, with the youngster set to undergo a medical and complete his move on Wednesday.
Juventus wanted a buy-back clause as part of the deal, but instead they will have the chance to match any offer Everton receive for the 19-year-old.
Now, The Daily Mail report Arsenal did attempt to hijack the deal in its closing stages by contacting both Juventus and the player’s agent, Mino Raiola.
Kean is said to have chosen Everton due to fears he would not be provided with regular game time at the north London club.
Marco Silva reportedly intends to make Kean a key figure in his plans for the forthcoming campaign, while at the Emirates, the 19-year-old would have to compete with Alexandre Lacazette and Pierre-Emerick Aubameyang for the no.9 spot.

Kean burst onto the scene in Serie A last season with seven goals in 17 appearances, but he was unable to cement a starting spot due to the presence of Cristiano Ronaldo, Paulo Dybala and Mario Mandzukic in the Old Lady’s ranks.
The return of Gonzalo Higuain at the club has also made it difficult for Kean to improve on his first-team chances.
And it is believed Kean’s arrival could spark a late flurry of activity in the transfer market at Goodison Park.
Everton have already signed Andre Gomes, Fabian Delph and Jonas Lossl from Barcelona, Man City and Huddersfield respectively this summer.
Meanwhile, Italian football correspondent Sheridan Bird believes Kean is a great coup for Silva and Everton.
“He does have an eye for goal. He has got ice in his veins,” he told talkSPORT 2.
“When I saw him last season he didn’t need many chances to score.
“He is a very tidy finisher and didn’t at all get overwhelmed last year despite his young age and playing for Juventus.”
The Hammers have been left with plenty of time to find a replacement.
But who could they target? talkSPORT.com has identified five potential replacements for the forward…

Moise Kean (Juventus)
Recent reports suggested Everton were interested in signing Juve youngster Moise Kean – but if there is any sense at the London Stadium, West Ham will make a move for the striker.
Kean, who was the first player born in 2000 to debut in Serie A, would have hugely benefited by playing with Cristiano Ronaldo last season.
The teenager netted a solid six goals in his 13 Serie A appearances last season.
However, following the return of Gonazalo Higuain to the Old Lady’s squad and Paulo Dybala and Mario Mandzukic available, it is difficult see Kean getting much game time with the Italian champions next season.
West Ham should at least attempt to sign him on loan, with an option to sign him permanently at the end of the campaign.
And so with a solid defence, Silva is believed to be on the lookout for more attacking options.

Kean, who was the first player born in 2000 to debut in Serie A, would have hugely benefitted by playing with Cristiano Ronaldo last season.
The Italy Under-21 star could seamlessly fit into an Everton side that will be pushing for a top six spot next term.
This was Silva’s preferred formation as Everton finished eighth after a horrendous start last season.
Kean could play the lone striker role and bring Bernard, Sigurdsson and Richarlison into the game with his hold-up play.
This formation could see Calvert-Lewin or Richarlison, depending on the opponent, offer Kean more support up front, while allowing attacking full-backs Seamus Coleman and Lucas Digne more opportunities to roam forward.
Sigurdsson, playing slightly further back than usual, could be the team’s deep-lying playmaker.
Kurt Zouma would be Everton’s third centre-half if they are able to sign him on a permanent deal from Chelsea.
And despite the incidents in Serie A during the season, Ranieri told La Gazzetta dello Sport: “The racism you hear in stadiums is just something very silly to mock, in a very, very stupid way, a lad whose skin colour is not as light.
“It’s silliness. I don’t think there is real racism in stadiums, or at least it’s only a very small part of it.”

Cagliari will face no punishment for the racial abuse their fans hurled at Juventus striker Moise Kean.
The teenager was subject to racist taunts from the crowd during the game when Juve travelled to the Sardinian club for the Serie A clash in April.
He held his arms out after scoring Juve’s second as they won the match 2-0.
The celebration appeared to be in reaction to the chants and he was then subjected to further abuse.
His team-mate Blaise Matuidi threatened to walk off during the match as he was also on the receiving end of abuse.
Serie A released a statement on Tuesday saying it had decided not to sanction Cagliari over the incident.
“The chants, even if they were reprehensible, objectively had a limited relevance to the game, even considering the perception,” the statement read. “The decision is not to apply sanctions to Cagliari.”
