The Czech Republic international was linked with a move away from the Emirates Stadium in January, but impressive showings against Tottenham, Liverpool and AC Milan have convinced the north London club to tie the playmaker down with a new deal.
The attacking midfielder expressed his joy at extending his stay with the team, and is happy to commit his future to Arsenal.
“It’s a great honour to sign a new deal with Arsenal, I love the club and am proud to wear the Arsenal shirt,” he told the club’s official website.
“It’s felt like home since I arrived six years ago and I couldn’t be happier to commit my future to the team.
“The manager, my team-mates, the staff and the supporters – everyone plays their part in making this a great club, and I feel privileged to be a part of it.
“I believe we have a really talented group of players and, together with the manager, the future looks bright.
“It’s always been my goal to win trophies here at Arsenal, and I will fight hard to achieve my dreams here,” he confessed.
Arsene Wenger was also delighted to keep Rosicky at the club, and has revealed his admiration for the player’s abilities.
“I’ve always been a big admirer of Tomas’ abilities and am delighted he’s chosen to commit his future to the club.
“I believe he is an exceptional player, a natural footballer who is technically top class.
“He plays the style of football we champion here and shares completely our philosophy. He is always ready to work for the sake of the club, always willing to put the team first. I have huge respect for him,” the coach concluded.
