Aston Villa midfielder John McGinn is backing Kieran Tierney for success with Arsenal.
The fullback moved to the Gunners last week from Celtic.
“He's got everything," McGinn told talkSPORT.
“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."
