Injuries to Alexis Sanchez and Aaron Ramsey worry Arsenal's Wenger
Arsenal manager Arsene Wenger was left counting the cost of his side's 2-1 victory over Leicester on Tuesday after both Alexis Sanchez and Aaron Ramsey were forced off with injuries.
Sanchez, who has only just returned from a two-week lay-off with a hamstring strain, took a knock to his knee in the first half at the Emirates Stadium and had to be replaced in the 68th minute.
Ramsey came on as a substitute in the second half but lasted only nine minutes before going off with what Wenger suspected was a recurrence of a hamstring injury.
"Sanchez got a knock on his knee," Wenger said. "From the moment he got this knock, he was never really comfortable. I don't know for how long he will be out and whether he will be out or not. I haven't seen the doctor."
On Ramsey, Wenger continued: "It looks like it (a recurrence of a hamstring injury). I don't know how bad it is yet.
"Just visually, it didn't look good - when a guy stops straight away and sits down, that's not good news. There's a recurrence now of a few muscular injuries and it's difficult - we haven't found out why."
Wenger admitted he was ready to take Sanchez off at half-time but the Chilean insisted he was capable of playing on.
Arsenal were able to overcome their fitness concerns as first-half goals from Laurent Koscielny and Theo Walcott were enough to seal a valuable three points.
Andrej Kramaric created a nervy finish after pulling one back for Leicester, whose second-half display suggested the team remain behind their under-fire manager Nigel Pearson.
"Leicester are fighting not to go down and when you see the way they play football, you are surprised they are bottom of the league and they want to get rid of their manager," Wenger said. If they keep quiet, don't panic and stick together they will get out of that.
"For me they are one of the better sides we have played at the bottom of the league."
