Arsenal manager Arsene Wenger has suggested that Wales are partly at fault for the recent hamstring injury suffered by midfielder Aaron Ramsey.

The 24-year-old is expected to be sidelined for around a month after pulling up during the Gunners' 2-0 victory over Bayern Munich in the Champions League on Tuesday night.

While officially ruling out Ramsey from this weekend's Premier League match against Everton, Wenger also admitted his frustration that the midfielder played the full 90 minutes of his nation's Euro 2016 qualifier against Andorra last week.

"He had a scan today but he's out," Wenger told the club's official website. "I believe he will be out until after the next international break.

"With the [last] international break, the fact that he played against Andorra certainly cost [Gareth] Bale and him as well."

Overall, Ramsey spent 11 weeks out of action last season due to hamstring problems.
