Bertrand was part of the squad that won the Champions League in 2012, starting also in the final, but failed to impress after that and was sold to Southampton for £12m in summer 2014, establishing himself as one of the best full-back in the Premier League since then.
“When you look at the players he has at his disposal, he has very intelligent footballers,” Wilkins told Sky Sports.
“Therefore it shouldn’t take too long to get over how he wants them to play.
“Victor Moses has been a revelation at Chelsea this season.
“But I’m not too sure about Alonso on the left hand side.
“I would prefer Ryan Bertrand there but they sold him for £10m and brought in Alonso for £30m.
“I can’t quite add up that maths. They would be stronger down the left with Bertrand.”
