Arsene Wenger says Arsenal will only buy if an exceptional solution arises after defeat against West Ham

Arsenal manager Arsene Wenger has insisted the Gunners will only sign further players before the end of the transfer window "if an exceptional solution turns up" while refusing to blame former Chelsea keeper Petr Cech for the defeat against West Ham on Sunday 9 August.

The Community Shield winners started the Premier League campaign with a disappointing 2-0 home defeat against the Hammers after Cheikhou Kouyate and Mauro Zarate took advantage of two mistakes from the new Arsenal keeper to score the goals.

And after both Olivier Giroud and Theo Walcott struggled to make the most of their chances up front some reopened the debate over the necessity of signing a top striker, amid reports linking the club with a record move for Real Madrid star Karim Benzema.

Wenger, however, claimed that his position regarding the transfers will not be affected by the defeat against West Ham.

"I would like to think that we are responsible to buy the players and the coaches, not the media. When you're a pro footballer, you have to face your responsibilities and not always look at something else. Today we have to look at ourselves and think we were not good enough and not to think that these kinds of things are solutions for us. We were not good enough, we were not convincing," he said.

"And that's basically it. West Ham played well. Congratulations to them and hopefully we can bounce back quickly. Again, I can only repeat what I already said. If an exceptional solution turns up, we'll do it. But after a defeat like that, it's important not always to think we take a solution from outside."

Meanwhile, Wenger points out that the whole team was unconvincing, refusing to question Cech's performance.

"I haven't spoken to him (Cech) yet. I can't see many individual convincing performances today so it's difficult to single someone out," he said.

"I [haven't analysed the goals] yet, no."
