Arsenal saw themselves down 1-0 at Upton Park against West Ham on Boxing Day, but Arsene Wenger's squad was able to turn the result. A double strike from Theo Walcott was just the icing on the cake, before Lukas Podolski netted a third, and sent the Gunners on their way.
Now top of the table, the Premier League leaders head to St. James Park, but without Aaron Ramsey. The Welsh international is the club's leading scorer with eight goals in the EPL.
Per Mertesacker is confident with Arsenal's current squad, but he believes they need to add a few more pieces in January.
"We need the right additions," Mertesacker told Arsenal Player. "We said that a lot in the summer then Mesut Özil came, but at this time, in a very special period that only happens in England, you need to get the right additions with players who come back from injury," he added.
"We lost Aaron Ramsey, so a good player is maybe out two or three weeks, so we need the right additions now. We have a good squad, and that is going to be vital in the next couple of weeks."
