Former Arsenal defender Mikael Silvestre says they must rethink selling Kieran Tierney.
The fullback is expected to leave the Gunners this summer with Newcastle and Aston Villa keen.
But Silvestre told bettingexpert.com: "I think it's important that Arsenal find a way to retain Kieran Tierney.
Fighting for the title, playing in the Champions League again, you need two international level players in almost every position.
So, they need to find a way to convince him that he's part of the plan for next season.
But Silvestre admitted: "He should have a lot of clubs looking for him because it's hard to find a player to play left-back these days
The Premier League, he has the attribute to play for any team and it makes sense for Villa and Newcastle to be chasing him."
