Cesc Fabregas believes he has surpassed the level he was playing at with Arsenal and Barcelona and is now playing the best football of his career at Chelsea.

Fabregas, 27, has been integral to Chelsea's unbeaten start to the season, which has seen them open up a six-point gap at the summit of the Premier League.

The Spain international has been at his creative best in that time, providing 13 assists in 17 games in all competitions having seamlessly readjusted to life in England.

And, speaking to Spanish radio station Candena Cope, Fabregas acknowledged his game has reached new heights at Stamford Bridge.

He said: "I'm possibly playing the best football of my career, I'm getting a lot of the ball and my confidence is growing. I'm playing with a style that suits me and in a position that I like. I feel free."

During the interview, Fabregas also responded to comments recently made by Sergio Ramos after the Real Madrid defender questioned his commitment to the Spanish national side.

Fabregas and his Blues teammate Diego Costa both withdrew from the Spain squad with injuries and missed La Roja's recent European Championship qualifier against Belarus and the friendly with Germany as a result.

Both players were back in action for Jose Mourinho's side on Saturday 22 November, however, prompting criticism from Ramos, although the Real defender later claimed his remarks were not aimed at Costa or Fabregas.

The former Arsenal skipper was not buying that, however, and although Fabregas maintains he and Ramos have buried the hatchet, he has urged his countryman to speak to him directly next time he has a problem.

"Yes, I felt offended and told Sergio how I felt," Fabregas continued.

"We eventually spoke on the phone and all is fine. It really irked me that my level of compromise was doubted. I've played many times and been involved in call-ups without playing. I've played 94 games for Spain over the past nine years and have always shown up... always and always in good faith.

"I had tendinitis in my left hamstring. If I played I could have ended up with an injury not too dissimilar to that of Modric. I told Ramos at the time that if he has something to say to me then he should pick up the phone and call and not send messages via the media. We've been playing together since the U-21 days."
