Frank McAvennie has warned Arsenal could lose Kieran Tierney if they don’t match his lofty ambitions.
The former West Ham hitman, speaking exclusively to Football Insider, insisted the defender can become the best in the world in his position.
Arsenal finished a disappointing eighth in last season’s Premier League though Tierney, 24, was a shining light.
The Scotland international made 27 appearances at both left back and centre back.
He missed a run of games with a knee injury in early 2021 but returned for the club’s run in.
McAvennie insists Tierney can become one of the best players in the world and told Arsenal to match his ambition.
He also warned Arsenal can’t afford to suffer another poor season.
“The best signing they made in recent years is KT,” McAvennie told Football Insider correspondent Ben Wild.
“He’s been magnificent. They have managed to get him fit and he really is something.
“If they aren’t careful, he’ll leave. He’s destined for the top, I really believe that and Arsenal can’t give that to him.
“They are going backwards. I’m looking at the left back at Man City and my god, Tierney could step in there easily.
“He could do it in any team in the world, he can be the best left back in the world. Arsenal have to step up and match him.
“A lot of players will be asking questions this summer because they are going backwards.
“Arsenal can’t afford another bad season.”
Tierney joined the Gunners from Celtic in the summer of 2019.
Since moving to North London he has won the FA Cup and the Community Shield.
