Alexis Sanchez has given Arsenal a major boost by revealing that he is “very happy” at the club.

The Gunners forward is about to enter the last 18 months of his contract with Arsenal and there are genuine fears at the club he could be looking to wind his contract down in view of joining another major European club.

However, the Chile international insists he loves the playing style developed by Arsene Wenger at Arsenal and is happy where he is following the team’s fine start to the season.

“The truth is yes. I love this style of play and I am very happy to be with the club,” Sanchez told ESPN. “I have adapted well, the team moves the ball better.

“And what I like is that when I go out to put on the pressure, the entire line runs in behind me together. And I like that. And depending upon the pressure that I put on, the team follows me from behind. And that is great.

“I love the football here [in England]. It’s back and forth, attack and defend, attack and defend. The fans love it and it is fun to watch as well.”

Sanchez’s words will placate Arsenal fans fearful that the team’s talisman may not be planning to extend his contract.

Arsenal are unbeaten in all competitions since the opening day defeat against Liverpool and are currently just two points off the pace in the Premier League and have already qualified for the last 16 of the Champions League.

Sanchez has been a big part of the team’s impressive run of results, scoring eight goals and supplying seven assists from 15 appearances in all competitions.

Arsene Wenger has decided to use the Chile international to spearhead Arsenal’s attack this season and he is currently keeping Olivier Giroud out of the starting XI.

But Arsenal are waiting nervously on the latest bulletin from Chile on Sanchez’s condition after he suffered a hamstring injury while on international duty earlier this week.

TheLondon club’s medical team have been in contact with their south American counterparts since Sanchez pulled up with the problem in training before his country’s World Cup qualifier away to Colombia on Thursday.

The Chile football association has described the injury as a “low-grade muscle tear” and has said that Sanchez will not travel to Colombia.

He will remain in Santiago for treatment and assessment, in the hope that he can be fit for Tuesday’s qualifying tie at home to Uruguay.

The potential loss of Sanchez for an extended period of time would be a massive blow for the Gunners.

In other Arsenal news, Hector Bellerin has given the club a boost by signing a new six-year deal worth over £31.2million.
