Arsenal manager Arsene Wenger has given an update about the injury concerns which are prevailing at the club.

Wenger told the media that there are not many injury troubles at the club except for Per Mertesacker. He said, ‘Mertesacker may still be a bit short’.

Speaking to the media the French manager said: “We have no injuries and we left Ramsey and Bellerin behind [for the Zagreb game]. They integrate into the squad again. Mertesacker may still be a bit short, I have to decide that today (Friday).”

On Mertesacker and Wilshere. Wenger opined:  “It was an illness for Mertesacker.

“Jack will have surgery next week and it is a blow, a big problem. But on the short term only because it does not damage his future.”

Arsene Wenger further said that the win against Chelsea earlier in this season in the FA Community Shield was a great confidence booster. It was also the Frenchman’s debut win against fierce rival Jose Mourinho.

He further added: “For me, what is important is that Arsenal win games. It can sometimes be a mental block for the players or the team when they do not win against certain teams. On that front, it was good [to win the Community Shield].”

“What you expect from these kinds of games is [that they are] always high intensity, full commitment and, of course, you want to prepare for that and play with a full focus.

“For us it’s a big game. Let’s not forget it’s the start of the season and only five games have been played. We know our position at the end of the season will depend on how well we do in the big games.

“I do not think too much about where Chelsea stand in the league at the moment. I focus more on us performing well, with full power.”

About Petr Cech Wenger said: “He will give a little bit of extra [insight], yes. There is no big secret, but on the day you have to perform at your best and perform together.

“Our individual performances will be more important than what he knows. There is no massive secret in that.”
