Injured Arsenal pair Shkodran Mustafi and Aaron Ramsey ruled out of West Ham derby

Arsenal will be without Shkodran Mustafi and Aaron Ramsey for Wednesday's Premier League trip to West Ham.

Mustafi missed Sunday’s 1-1 draw at Southampton after limping out of the previous weekend’s defeat to Manchester United with a thigh injury.

He had been expected to recover in time to face the Hammers but Wenger said: “[He will be out] a little bit longer. He’s out in training, running. The medical staff have decided that he’s not completely ready. Will he be ready for Saturday against Newcastle? Yes.”

Ramsey sustained a hamstring problem at St Mary’s Stadium and is unlikely to be available for this weekend’s home game against Newcastle.

“It’s normally a short period,” he said. “It’s not a big one.”

Asked if he will rotate his team, Wenger told Standard Sport: “I will have to look first of all at how some players have recovered. We look at how much energy they spend, how they recover and after I make my decisions, adding to that the balance of the team.
