Arsenal boss Arsene Wenger has confirmed that he is worried Aaron Ramsey may miss the entire Christmas fixture list.
The Wales international picked up a small hamstring injury against Galatasaray in the Champions League and was substituted to minimise the risk of making it worse.
Arsenal won the match 4-1, but it's clearly come at a cost as Ramsey may now miss the fixtures over the next few weeks with a return just before January possible.
"I am scared he [Ramsey] will miss the Christmas period," Wenger told his press conference ahead of the Liverpool match on Sunday.
"He should be back at the end of December, or beginning of January."
Ramsey scored a brace in the first-half as Arsenal took Galatasaray apart in Turkey before the Welshman was withdrawn at half-time after suffering the injury.
Ramsey has three goals and two assists through 14 Premier League appearances so far this season, and he will miss the trip to Anfield and the home tie against Queens Park Rangers five days later on Boxing Day.
When could he be back?
If he recovers quickly, then Wenger could rush him back for the visit to Upton Park to face West Ham United on the 28th December although it sounds like Wenger believes the visit to Southampton on New Year's Day or the home match against Hull City on the 4th January are more realistic targets.
Elsewhere on the injury front, Arsenal may have Theo Walcott back to face Liverpool, while Laurent Koscielny is definitely out.
Walcott will undergo a pre-match fitness test to gauge his availability for the match, as will midfield teammate Alex Oxlade Chamberlain.
