Aaron Ramsey out for at least three weeks with hamstring injury

Arsenal will be without Welsh midfielder Aaron Ramsey until the end of November after he suffered a hamstring injury during his side's Champions League win over Bayern Munich on Tuesday.

Ramsey, who struggled with hamstring problems last season, was forced off in the 57th minute and manager Arsene Wenger said and Ramsey was "very down" about his latest setback.

He had just begun to get back his best form, scoring in his previous two matches for club and country.

Wenger suggested Ramsey may have picked up the injury as a result of his busy schedule, having already made 17 appearances so far this season.

“He had a scan today but he’s out. 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,” Wenger told the club’s website (www.arsenal.com).

Former Tottenham Hotspur player Bale came under fire from Spanish media, with suggestions he had put Wales in front of his club side Real Madrid by playing against Andorra when Wales had already qualified for the Euro 2016 finals.

Ramsey will miss Saturday’s game against Everton, as well as the North London derby against Tottenham Hotspur on November 8th.

Wenger also confirmed back-up goalkeeper David Ospina is likely to be out for the same duration.

Meanwhile Scottish champions Celtic have signed free-agent striker Carlton Cole until the summer of 2017, the club said on Thursday.

Cole, 32, was released by West Ham United at the end of last season after nine years with the London club.

He has scored 85 goals in 384 games across five clubs during his time in English football.

Cole also has seven England caps but was never on the scoresheet for his country.
