Laurent Koscielny: Why I’m one of the best in the Premier League

The Gunners, defeated 1-0 by Chelsea last time out, are now third, trailing leaders Leicester by three points and below second-placed Mancehster City on goal difference.

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

Arsenal forward Alexis Sanchez seems to be coping with his side’s fall from the top of the Premier League table pretty well as he played with a pair of gold retriever puppies.

“He was one of the players where the energy and intensity hits you straight in the face”, he told the club’s official website.

But, with a gruelling run of games away from home still to come in the league, Koscielny knows how important home success, including Sunday’s visit of their London rivals, will be.

The Gunners will move back to the top of the Premier League if they manage to beat Chelsea on Sunday, while the club are searching for their first Premier League title since 2004.

It was a big weekend in the Premier League title race as leaders Arsenal lost at home to Chelsea.

The pair have been in first-team training this week, however, and they are both likely to play a part in the game at the Emirates Stadium.

Arsenal manager Arsene Wenger believes Diego Costa instigated yet another red card, much like he did in their previous encounter.

When he finally got to work with Sanchez at Arsenal, Wenger was struck by the Chilean’s energy levels again, saying: “I think his enthusiasm is absolutely fantastic and his desire, and the fact he fears nothing”.
