With the Premier League title race entering the final straight, Arsène Wenger says Arsenal cannot afford any more “weak moments”.

The Gunners are third in the table and could find themselves 10 points behind leaders Chelsea by the time they face Tottenham on Sunday afternoon.

Wenger accepts his side face a major challenge at White Hart Lane, and must be fully focused if they are to beat their north London rivals.

“We have played two draws and three losses there [in the last five league meetings],” the manager said. “It is a difficult ground to go to for everybody.

It has always been difficult at White Hart Lane but we are in a position where of course we want to win the game

“It has always been difficult at White Hart Lane but we are in a position where of course we want to win the game.

“After Stoke it was very important that we had a good result against Everton, we had a good result even at Bayern but [it remains important] that we continue and have no weak moment any more until the end of the season.”

Tim Sherwood has come under pressure in recent weeks after publicly criticising his players, but Wenger has sympathy for his opposite number.

“I think he said that the performance was not right, and I say that as well sometimes,” he said. “For the rest I think he is dealing with it well.

“There was an incident during the [Tottenham v Benfica] game, and I think he was right personally because he had been provoked in an unfair way. Overall he handles the [whole] situation well.

“Tottenham have bought so many players that it might take them some time to get the right balance or find the right level. I think they are a good side.

“I still think it always takes time when you bring in many new players, but you cannot say Spurs have had a bad season, they’ve had a good season and they are there.

“Like everyone else, like we have, they have gone through good and bad periods.”
