England Under-21 defender Ryan Bertrand has the unenviable task of challenging England and Chelsea defender Ashley Cole for the left back position at Stamford Bridge. However, 21-year-old concedes knows there is no better player to learn from, with the 30-year-old considered by many to be the best left-sided defender in the world.
"It's a massive positive having him at Chelsea - and a massive hindrance too I suppose!" said Bertrand, who joined the Blues aged 15.
"He's definitely right up there - his attitude, the way he goes about training. He's won the most FA Cups, and a lot of other silverware, and to still have that attitude at his age is fantastic."
"He's a fantastic role model, despite all the stuff that gets written about him. He's a brilliant man and a brilliant player to have around to help you with your game.
"If I ever have anything to ask him about a certain situation on the pitch, he's more than happy to come back and talk."
Bertrand admitted he sometimes wished he was a right-back as he prepares for another season where a loan move could be his only hope of regular first-team action.
"Every player has different paths and mine so far has been out on loan," added Bertrand.
"You've seen the benefit for Scott (Sinclair). He's gone up this year with Swansea and it's been fantastic for him."
But asked how long he was prepared to wait for his own chance at Chelsea, Bertrand said: "I'm just concentrating on the near future."
