A couple of reports have been doing the rounds in recent weeks suggesting Alexis Sanchez is unhappy at Arsenal. The Chilean forward seemingly cleared this up today by sending out his first tweet, with a picture of him celebrating in his Gunners' shirt.

Sanchez has scored an impressive eight goals in 15 appearances for the Gunners since signing from Barcelona for £35m this summer.

Reports from Spain have claimed that Sanchez is unhappy, however the 25-year-old looks to have played this down with his first foray into the world of Twitter.

In addition, the Gunners' captain Mikel Arteta has said that Sanchez "feels comfortable" at the Premier League club.

"It's a different culture and language for him so he doesn’t necessarily understand what we are saying at some times but he wants to play football and I think he feels comfortable as well," Arteta told arsenal.com.

Arsenal face newly-promoted Burnley at the Emirates Stadium on Saturday.
