Arsene Wenger revealed that Arsenal are doing their best to make new signings before the transfer window shuts, while reserving special praise for Theo Walcott and Aaron Ramsey for their performances this preseason.

The Gunners are believed to be closing in on a move for Brazil midfielder Luiz Gustavo, having tabled a bid to Bayern Munich.

Arsenal are also still hopeful of completing a move for Luis Suarez from Liverpool, while the likes of Julio Cesar and Mathias Ginter continue to be linked with moves to the club.

Arsenal fans always say we will only believe the signing is done once it is up on Arsenal's official website, and according to Wenger the club are making every effort to bring in new faces to the club as soon as possible.

"We are in the transfer market and we try still to strengthen our squad," Wenger told Arsenal Player.

"It's important as well now to focus on the squad who are already at the club and that you focus on the competition, not only on the transfer market."

Meanwhile, Wenger was quite happy with the performances of Walcott and Ramsey, particularly in the 3-1 win over Manchester City in the final preseason game at the weekend.

"It's important to be confident, especially when you score three goals," Wenger said. "It's good to keep the urgency high as well and I think we will do that. The team has a good attitude, good spirit and you could see that again here.

"Walcott put in a great performance. I'm happy with both sides of his game - he defended very well and (set up) two goals. His game has improved tremendously because he's an intelligent player. When you're intelligent, you always improve.

"I have always believed in Aaron and I think he has shown again what a tremendous engine and what desire he has. His vision has improved and his tactical aspect has improved a lot. He's growing into a very strong player."
