Chelsea midfielder Oriol Romeu admits it was a great experience training with Barcelona's superstars.

Romeu left Barcelona B for Chelsea in the summer.

He told the Guardian: "For a young player to have spent even three or four training sessions on the same pitch as Messi, as Xavi and Iniesta, is unbelievable. Something you dream of. We usually trained separately but when we were asked to join the seniors it was incredible. To be playing with Messi ... When you give him the ball you have no idea what he will do with it. He's capable of anything.

"I only played one competitive match alongside him [against Sevilla in the Super Cup] and he came on after an hour and started dribbling round their defenders for fun. They tried but couldn't stop him but he made it look so easy. I was there thinking: 'Wow, that's impossible.' But he does what no one else can, even without thinking.

"Even with everything they've achieved in the game, those great players are focused purely on winning. That's what you need, that hunger to keep winning games, and you cannot help but learn from them. It's the same here. I came to Chelsea to be a part of a big team, with big players, and to learn from them all.

"Players who have been at the top for five or six years can teach you so much. I have learned so much already: the mentality you need to bring to training every day, even the way you carry yourself in the dressing room."
