Arsenal legend Kenny Samson has urged Southampton youngster Luke Shaw to follow the example of Chelsea star Ashley Cole.
The former England fullback is a big fan of Shaw.
Samson told the Daily Mail: "Luke will know, if he's picked, that he probably won't start at the World Cup. If that happens, he's got to look up to Baines or Cole and say to himself, 'I want to be better than you'.
"From the age of 18, every season you should add something to your game. It might be that you read the game a little bit better. It might be learning to time your jump. It could be the smallest thing, but it's important.
"I used to watch Ashley when he came into the Arsenal side and he'd get caught on the inside trying to tackle with his left foot, going across his body. He gave a few penalties away like that, but he worked on it until he could tackle with his right foot.
"Whenever he had a slight problem, Ashley worked hard at it. That's the attitude that's got him 100 caps. Without it, there's no way he'd have got 100 caps. He's worked hard.
"I think Glen Johnson went through a period when he thought he'd arrived and he didn't play so well, then he went to Portsmouth and realised he had to pull his finger out because he hadn't quite made it yet. He's improved from there to become a very good full back."
