The Czech Republic international's current deal expires at the end of the season, but the Gunners manager says his midfielder will still be at the Emirates next season.
The Czech midfielder is free to discuss a move elsewhere in the current winter transfer window, but has stated his desire to extend his nearly eight-year stint at the Emirates Stadium. And Wenger has confirmed that he expects Rosicky to remain at the club, and praised the former Borussia Dortmund man's quality.
"Tomas will stay here at the end of the season," the French coach told reporters on Friday. "He is a marvelous player and contributes well to the team. He is certainly a typical Arsenal player in the way that he is mobile, technically sound and team-orientated. He is a fantastic footballer."
Rosicky has made 20 appearances in all competitions for the Gunners so far this season, and should be in the squad for Monday's game at Aston Villa.
