Mesut Ozil will be even better during his second season in the Premier League, Arsenal team mate Per Mertesacker has said.
Ozil, who arrived from Real Madrid for £42 million last summer, has faced criticism after failing to sustain his early-season impact.
"He has adapted well but there is more to come from him, and I think the second season will be much better from him, because he's a fantastic player," Mertesacker told Arsenal's official website of his Germany colleague.
"He has shown some great skills but he needs to be more consistent, and that's what makes the difference at the end.
"With a pre-season ahead of him, there's more to come from him."
Arsenal's record signing Mesut Ozil shrugged off criticism over his former club Real Madrid today, and said he was happy in London and ready to "taste success" under Arsene Wenger.
The 24-year-old scored 19 goals in 104 La Liga games over three seasons before joining the London club for £42.5m.
Mesut Ozil said: "I had three great years in Madrid and that is all I will say... If you look at my statistics [in Madrid] and how many games I played there then you can see how professional I was.
"I feel great in London, the coach gives me the trust, the team is fully behind me and I feel very very well there. I can only say that he [Wenger] is a great coach who knows exactly what he wants and has a clear vision. We need a coach like that if we want to be successful."
Mathieu Flamini says a new-found determination has helped transform Arsenal's early-season form following the disappointment of a 3-1 home defeat by Aston Villa on the opening day of the new Premier League season.
Arsenal Midfielder Mathieu Flamini says the club's record signing Mesut Ozil could be the missing ingredient which helps end Arsenal's long quest for silverware. Ozil was instrumental in he club's 3-1 victory over Stoke on Sunday.
Mathieu Flamini said: "Eight years without winning anything is not easy for anyone, for the fans, for the players, for the club or the coach, but the quality is here... We knew Mesut was a big player - he proved it at Madrid.
"For us, it is a great boost because he is a great player and knows how to make the difference. He has great spirit, he is working hard for the team and can make the difference at any moment."
Mesut Ozil said he was now part of the strongest league in the world, and had a lot to prove.
Mesut Ozil said he "felt great" to be part of the team at Arsenal and was confident Arsene Wenger would help him improve as a player.
Arsenal's record signing Mesut Ozil has defended his professionalism after making a surprise departure from Real Madrid. The player's £43million move on transfer deadline day was met with disbelief from several former team-mates at the Bernabeu.
Today Mesut Ozil insisted he would not let anything affect his fresh start in London. He said:
"I don't want to say anything bad about Madrid because I had three wonderful years there. I have great friends there. We achieved a lot with the club and (won) trophies. That is why I don't want to talk a lot about it.
"People who know me know how professional I am and I think [in] the past years, you can see how many games I played - 159 games. If you are not professional in your life, then I don't think you can play that many games.
"People know how professional I am and this is what counts. All the rumours, I don't care about them. I have a new task here. I am just looking ahead."
