Tomas Rosicky says Arsenal can definitely end their trophy drought this season and that he would have left the club if he didn't think they could.
Gunners manager Arsene Wenger revealed on Saturday that an agreement had been reached with the 33-year-old over a one-year extension to his current deal, which expires in the summer, and that an announcement would be made soon.
It is a boost for the Emirates Stadium club as Rosicky has made himself a crucial member of Wenger's squad since returning to play regularly after nearly two years out.
Arsenal are one point off the top of the Premier League table, in the FA Cup quarter-finals and the last 16 of the Champions League, meaning they are probably facing their best chance of a trophy for a number of seasons.
Rosicky is sure they can end the nine-year drought this season or next and said it was a motivating factor behind his decision to sign an extension.
"I always believed in it here at Arsenal and still do. I knew this club was the right place for me and I want to be here for as long as I can," he told the official Arsenal magazine.
"It is obviously very difficult to predict how long I can go on for, (but) I feel very good. I don't feel any different than in the past, I don't feel any change in myself.
"I won three titles in the Czech Republic before I left (Sparta Prague), I won the Bundesliga with Dortmund and I still believe I can do it here. I wouldn't stay here if I didn't believe."
