Arsenal forward Alexis Sanchez has claimed that the club are capable of winning the Premier League, FA Cup and Champions League this season.

The Chilean, who is preparing to mark his return to action after spending almost two months out with injury, is targeting the treble but admitted that the feat "will not be easy".

The Gunners are defending champions of the FA Cup and are considered to have a good shot of winning the league, but must overcome Barcelona in two legs to progress to the quarter-finals of the European showpiece.

"I am very happy at Arsenal and I'm not thinking about leaving," Sanchez told the club's official website. "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."

Arsenal will return to the top of the table if they defeat Chelsea at the Emirates this afternoon.
