Arsene Wenger made 11 changes as a Danny Welbeck goal was enough to seal a forgettable 1-0 win over the Hammers to put the Gunners into the Carabao Cup semi-finals.

Wenger has been rotating his team between the Premier League, Europa League and Carabao Cup so far this season and has bemoaned the lack of rest time his side has had relative to their recent opposition.

Both Giroud and Coquelin limped out of Tuesday's game, with Wenger anticipating Giroud will be out for up to three weeks with a hamstring problem.

With Liverpool visiting the Emirates Stadium on Friday, Wenger conceded he is concerned that he may see more members of his squad ruled out in the coming weeks as Arsenal enter a run of 10 games in 36 days.

"It is very demanding, especially because we already have a tough schedule behind us," he said. "We have to sit down and analyse very well what we can do. What is very worrying in my job is when you start to lose players, like Giroud tonight.

"After, you cannot afford to lose another one. I have to look how I can manage the schedule.

"When you look at our fixtures in January and February, you cannot imagine we will always play with the same players in every game.

"Will I change from Premier League game to Premier League or only in the Carabao Cup? I don't know yet - I have to look at the fixtures to see what I do."
