Aston Villa midfielder John McGinn is backing Arsenal defender Kieran Tierney for greatness at the Emirates Stadium.
The star was speaking on talkSPORT about his Scotland teammate, and believes the Gunners have a brilliant player on their hands.

Tierney joined Arsenal in a £25 million deal on transfer deadline day after weeks of speculation, and is expected to make his debut for the club in late September after undergoing surgery on a hernia this summer.
The 22-year-old is great business by the club in the eyes of McGinn, who obviously knows Tierney well from the international setup.
He said: “He’s got everything. Once he gets back fit, he will run through a brick wall for Arsenal.

“Not only that, he can gallop up and down the pitch and get assists, he’s a very good crosser of the ball.
“He’s also a really humble guy who will improve all the time.”
TBR’s view
Arsenal fans are already excited to see what Tierney can bring to the table and McGinn’s assessment will do little to keep them calm.
Tierney’s eventual integration into the starting XI will be a welcome thing for Unai Emery, with left-back having become something of a problem position for the club in recent years.

Nacho Monreal has done well in parts, but the ageing Spaniard has begun to play more as a left-sided centre-half in recent times, with Sead Kolasinac operating as the wing-back.
There have been some question marks over the Bosnian towards the end of last season, so Tierney’s arrival will be most welcome – especially after McGinn’s testimony.
