Premier League: Arsenal must maintain focus during final games to achieve top-four finish, says Arsene Wenger

London: Arsenal must avoid complacency and carry the intensity they showed in Wednesday`s win over Southampton into their three remaining games to achieve a top four finish in the Premier League, manager Arsene Wenger has said.

Arsenal`s 2-0 win at Southampton lifted them up to fifth place, three points behind fourth-placed City. While their final league position is dependent on the results of their rivals, Wenger said that his team must take it game by game.

"I don`t know more than you," Wenger told reporters after the game.

"But I believe that, for us, it`s important to maintain the focus and intensity in every single game. We`ll need another strong performance at Stoke. We came to a difficult ground today and we go to another on Saturday.

"We know we can only win our games... So let`s just continue."

Midfielder Alex Oxlade-Chamberlain had picked up a hamstring injury but Wenger said that the injury was not serious.

"It`s difficult to assess now after the game," Wenger said. "He is walking properly. It was tight, but it was not a knife."

"I didn`t see any incident where he had to stop in a sprint. It was more fatigue.

"It`s a hamstring problem, but we don`t know how bad it is."

Arsenal travel to Stoke City on Saturday and could move four points clear of fellow top four contenders Manchester United, who face second-placed Tottenham Hotspur on Sunday.
