Per Mertesacker believes that getting players back from injuries is as important as adding to the squad.

The Gunners fans were asking for a marquee signing last summer and it was not until late into the transfer window did Arsene Wenger pull out Mesut Ozil from his hat, someone who has completely changed the dynamics of Arsenal's season since his arrival.

The north London club are currently second in the league and will go top with a win over Newcastle whom they visit on Sunday. Arsenal still have a couple of high profile injuries which need sorting out, with Aaron Ramsey and Alex Oxlade-Chamberlain currently out of the side.

Mertesacker's point was highlighted by Lukas Podolski's return from injury, following which he scored the winner and assisted the second against West Ham after the Gunners came back from being a goal down to win the game.

Theo Walcott, who was out with an abdominal problem has come back and has scored four times in his last three starts in the league. The defender is hoping that Ramsey and Chamberlain all come back into the team soon and have a similar impact for the Gunners.

"We need the right additions. We said that a lot in the summer then Mesut Ozil 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 told www.arsenal.com.

"We lost Aaron Ramsey [against West Ham] so a good player is maybe out for two or three weeks so we need the right additions now. We have a good squad and that's going to be vital in the next couple of weeks.

"During the game we always believed in our strengths. We want to go on another good run so at the minute we are really proud we are really proud that we came back today and it shows our character," he concluded.
