Unai Emery said he is in the market for players with “commitment” in January after watching his side beat Blackpool 3-0 to advance to the FA Cup fourth round.
The Gunners swept past their League One hosts at Bloomfield Road on Saturday with two goals from teenager Joe Willock and one from Alex Iwobi.
Arsenal fans greatly outnumbered their Blackpool counterparts, with over 5,000 supporters making the long trip north from London, as Tangerines fans stayed away in their thousands in protest at the running of their club.
“I think the club is working for the possibility to take some players who can help us during these next four months,” said the Spaniard.
“Maybe the transfer market can help us with a centre-back, but it is not easy because also [Konstantinos] Mavropanos is coming back after injury. Also a winger, right or left, one player can help us in this position.
“We need players with commitment. We need players who are prepared for when the team needs them and they can step up.”
