Arsenal forward Alexis Sanchez has revealed he is happy at the Emirates and believes they can win an historic treble this season.

The Gunners will go back to the top of the Premier League with a victory against Chelsea on Sunday afternoon after progressing in both the Champions League and FA Cup.

Sanchez is set to return from injury for the visit of Guus Hiddink’s Blues this weekend and is in confident mood about his side’s chances across the board this season.

“I am very happy at Arsenal and I’m not thinking about leaving,” said Sanchez, signed from Barcelona in July 2014.

“The unity here between fans, club and players is enormous and the supporters have been fantastic. We suffer the defeats and enjoy the ­victories together.

“This campaign we are ­demonstrating that we are serious candidates for the Premier League title. I think there can be no doubt about our credentials to be ­champions this time.

“It’s true that we have lost important points that could have given us a bigger advantage in the table, but, overall, we are having a very good season.

“The spirit between the players is sensational and, when we do suffer a blow, we are able to overcome it. That’s very important.

“I am always ambitious in football and I still want to win three titles this season – the Premier League, the FA Cup and the Champions League. It will not be easy but we can do it.”
