When asked about what the move will do for the image of Scottish football, Christie, who played with him at Celtic said: “It’s definitely positive and, no pressure on him, but it would be even better if he goes down there and really shines.
“Not just coming from Celtic but all over Scottish football now, players are going down to England and doing really well, which hopefully puts to bed this myth that we are way behind them, and shows we are definitely up to scratch with the level of English teams.
Tierney was a hugely important figure in Celtic’s treble treble success and Christie believes the left-back will have a great contribution at Arsenal, too.

“I don’t want to put pressure on him, but I think he’ll do very well. Having played with him and seen him in training, I know how good he is and how powerful he is.
“For what you are expecting from a full-back in the modern game, he ticks all the boxes. Hopefully he can get fighting fit as soon as possible and really kick on down there because I think everybody would love to see that.”
Celtic manager Neil Lennon was powerless in trying to keep Tierney at the club, even after the left-back explained via Instagram: “It has been the hardest day or two of my life.”
On his own transfer activity after the sale of the 22-year-old, Lennon said: “It makes things a little bit easier in terms of maybe pushing the boat out a little bit more but we’re not going to break transfer records and spend silly money.
“We have targets in mind and we are working away on that sooner or later. We are looking at maybe two or three positions.
“We also maybe need to move a few players on to get them playing or make room in the squad. Until we do that, we may not look to bring anyone in just yet.”
His former Aberdeen team-mate, Ball, was shown a second yellow card and sent off for the foul.
A Celtic statement said: “Celtic Football Club can confirm that Ryan Christie has suffered multiple facial fractures following the incident during Sunday’s Scottish Cup semi-final at Hampden.
“Ryan is scheduled to undergo surgery on Thursday of this week. We are not able at this stage to give any specific indication on a timescale for his return to action but, of course, everyone at Celtic wishes Ryan all the best for his full recovery.
