His lack of involvement has prompted rumours that he could return to Sunderland in January, but he has played down that suggestion, saying he is excited by the opportunity to prove himself at Chelsea.

“We initially decided to go to Sunderland with great enthusiasm and excitement to get some minutes in the top flight and get some experience,” he told Spanish outlet RTVE.

“In the end, there was an injury [to Delap], and I had to return to Chelsea, now with great enthusiasm and training hard every day.

“When Nico said no [to returning to Chelsea from Bayern], they called me, we talked about it, and it was quick. In the end, I want to succeed at Chelsea. And that’s how it was.”

While he is pleased with the opportunity to prove himself at Chelsea, he admitted he found the back-and-forth frustrating.

“It was all a bit chaotic, but in the end, I’m a person who faces everything with the utmost positivity, and that’s how I faced it, now enjoying every moment, because a footballer’s career is short.

“And that’s what I’m doing, enjoying every moment that life gives me.”

“[There was] never disappointment [at leaving Sunderland]. I believe that every action I take in my career is because I want to.

“And that’s it, I’m going to fight in every training session, in every game, every minute I have to play as many minutes as possible.

“Now I’m at Chelsea, and that’s where I am. I’m from Chelsea, the best club in the world for me right now.”
