Arsenal's Ramsey ruled out for a month
Arsenal manager Arsene Wenger has revealed midfielder Aaron Ramsey could be out for up to a month because of a hamstring injury.
Wenger also suggested playing for Wales against Andorra could have contributed to the injury and predicted Ramsey would miss the friendly international with Holland on November 13.
The first game Ramsey will miss is the Premier League clash with Everton tomorrow.
"He had a scan today but he's out. I believe he will be out until after the next international break," Wenger said.
"With the (last) international break, the fact that he played against Andorra certainly cost (Gareth) Bale and him as well."
Ramsey and Bale both faced Andorra in a Euro 2016 qualifying match on October 13.
Ramsey was taken off injured in the 2-0 Champions League win over Bayern Munich on Tuesday, having played 90 minutes against Watford three days before.
Meanwhile, Everton midfielder Tom Cleverley is in contention to make his first-team return tomorrow as Roberto Martinez's squad nears full fitness.
Cleverley got his first run-out since sustaining an ankle injury in August when he played 60 minutes of an U-21 game on Tuesday.
And asked yesterday whether the summer signing would play in this weekend's match at the Emirates Stadium, Toffees boss Martinez said: "It is just a case of seeing how he reacts from the game on Tuesday.
"The next two sessions are going to be very important to measure that.
"I would say, from a medical point of view, 100 per cent he will be ready, but it is just trying to guess and work on his match fitness more than anything."
Winger Steven Pienaar - yet to feature for the first-team this term due to a hamstring problem - also played the opening half of Tuesday's contest, while full-back Bryan Oviedo completed the entire duration as he continued to build up his fitness.
And Martinez added: "It has been great to see them coming back so sharp and ready to add to the squad. That is very good news."
