Bradford City winger Billy Knott is looking forward to their FA Cup tie with former club Chelsea.
Knott admits he regrets the way things ended at Chelsea, ditched following a serious breach of discipline aged just 17.
The 22-year-old has matured since the days of being depicted as a teen tearaway.
"I do regret it. It was me in the wrong and I messed stuff up," he told the Daily Mail. "I could have learnt a whole lot more. I was young and naive. I always had belief in myself as a player, but you need more than that.
"Looking back, I would take so much more on board, because these players are the best in the world and I was training with them.
"The likes of Didier Drogba, Frank Lampard and John Terry, they get it right every single day. They enjoy it every day as well. That's the big thing - these guys have been at the top for so long yet love coming in to train. That's the key thing, you've got to love what you do to be the best."
