The veteran midfielder has admitted that he thought about an Emirates Stadium exit mid-season.
The 34-year-old has been on the Gunners’ books since moving to England from Borussia Dortmund in 2006 and has become a fans’ favourite at the Emirates Stadium.
However, with regular first-team football becoming something of a commodity, Rosicky has confessed that he was weighing up his options during the last transfer window.
"We've talked about it in September, October,” the Prague-born playmaker told iSport.
“Then the transfer market was closed, so I couldn't do anything. When in December I had not played a single game and the market then opens, it's obviously a very real issue.
“Then you start to think about whether or not it is time to leave. I was no exception, it was very real. But Arsenal said that I wasn't for sale and that was it.”
Rosicky has only started five Premier League games this season after playing a more significant role for Arsene Wenger’s men last term.
With the eastern European in the twilight years of his career, he has admitted that he could well leave North London at the end of the season.
"The rest of the season will go very fast, then we'll work it out,” he continued.
“Arsenal has another option on me next season, they have everything in their hands. When I get back from the national team, we'll begin to deal with it.”
The excellent form of Francis Coquelin in the Arsenal midfield has stifled Rosicky’s chances to play, even though the likes of Mikel Arteta, Aaron Ramsey and Jack Wilshere have been unavailable through injury.
Rosicky has made over 150 Premier League appearances in his time with Arsenal, but only has last season’s FA Cup success to show for his time in England.
