Rosicky signs new Arsenal contract
The club did not say how long the contract extension was as the 29-year-old, who returned to the Arsenal side in September after missing 20 months through injury, became the 15th player since May to sign a new deal at the Emirates Stadium.
"The last two seasons haven't been easy for me because of injuries but I feel it speaks volumes about the club's belief in me for this to be signed, and I truly believe I have a lot left to offer the club, my team-mates and all the supporters," Rosicky told the club's website.
"It's felt like home since I arrived here four years ago and I believe we're on the verge of achieving something special together."
Rosicky follows other big-name players to sign a new deal with the London club including Abou Diaby, Eduardo, Alex Song, Nicklas Bendtner, Denilson, Robin van Persie and Theo Walcott.
