Arsenal manager Mikel Arteta says the club do not need a “reset” despite only picking up one point from their past three Premier League matches.

The Gunners were beaten by Newcastle United last weekend, which followed a draw against Liverpool and defeat by Bournemouth.

The run of form has left the club seven points behind league leaders Liverpool, while a 1-0 defeat by Inter Milan on Wednesday means they are currently 12th in the 36-team Champions League table.

“I don’t think about [needing a reset],” said Arteta. “Nobody works harder than me, I guarantee you that.

“We don’t need a reset. In one particular aspect we need to go from 95 (effort) to 100. I will not tell you what that is.”

Arsenal travel to London rivals Chelsea in the Premier League on Sunday.

Martin Odegaard, who returned from an injury absence during the loss at the San Siro on Wednesday, will be in the squad to face the Blues.

However, Declan Rice, who missed the match in Italy, remains a doubt.

“I have to be very vague on [Rice] because there is no clarity on if he is going to be fit or not for the weekend,” said Arteta.

“He hasn’t trained yet and it is not clear yet whether he is going to be available.”

Arteta says while Odegaard is available a decision has not yet been made on whether he is fit to start.
