Arsenal’s Mesut Özil accepts he will always be an easy target for the critics and says he has nothing to prove to anybody.

The German World Cup winner answered the growing doubters with a masterful display in the 3-0 demolition of Aston Villa on Saturday. He swept in the opening goal and created the second for Danny Welbeck at Villa Park when deployed in a more central role by the Arsenal manager, Arsène Wenger.

The 25-year-old has continually found himself under scrutiny since becoming Arsenal’s £42m club record signing from Real Madrid on deadline day in September 2013.

However, Özil says he is not about to let anyone else’s opinion get in the way of his continued progress. “I don’t play to prove anything to anybody, I play for Arsenal,” Özil told the German news agency DPA. “I have the feeling that I am criticised more, that happened to me in the Bundesliga and also at Real Madrid.

“We have only just started the season [at Arsenal], we have new players in key positions. The collective game, which is something I have a lot to do with, cannot then just work well from one day to the next.”

Ozil added: “[Just] 10 weeks ago I was elected to the team of the season in England [via an internet poll on the Premier League website].

“I was world champion then. It was the summer break and after a few games [of the new season] everything is called into question again. This is strange, but I know what I can offer.”

Özil is likely to be one of several first-team players rested by Wenger for the Capital One Cup tie at home to Southampton on Tuesday night but should again be the key man for Saturday’s north London derby against Tottenham at the Emirates.

The cup tie could see a debut for the Colombia goalkeeper David Ospina, who has yet to feature after regaining fitness following a summer move from Nice. The Costa Rica forward Joel Campbell may be another deployed against the Saints, along with fit-again midfielder Abou Diaby.
