Tottenham fullback Kyle Walker admits he studies the game's greats to improve his own game.
"I watch Dani Alves [the Barcelona fullback] constantly on YouTube," he told the Mail on Sunday. "He's forever in the box. He's a big hero of mine. It's fantastic how he gets forward and also how he defends as well."
There are others, too, from a little closer to home.
"I study Gary Neville as well when he was still playing. Gary didn't have the best pace in the world but never got beat. If I can get my positioning right like he did, as well as everything else, then I hope to become the complete right-back, too."
