Arsenal and Wales midfielder Aaron Ramsey is expected to be out for four weeks with a thigh injury.
That timeline would rule him out of games in the Champions League, Premier League and FA Cup, while he would also miss Wales’ friendlies with Northern Ireland and Ukraine.
The 25-year-old was injured in last weekend’s 4-0 FA Cup win at Hull.
“His signs are quite positive,” said manager Arsene Wenger. “At the start I would say four weeks.”
