Arsenal confirmed on Monday that Tomas Rosicky has signed a new contract tying him to the London club beyond the summer, when his existing deal was due to expire.
Arsenal have not however disclosed the length of the new agreement with the Czech Republic captain, who struggled to make an impact at the start of the season but has been in excellent form recently, particularly in last week's 3-0 win over AC Milan.
"It's a great honour to sign a new deal with Arsenal, I love the club and am proud to wear the Arsenal shirt," Rosicky, 31, told Arsenal's 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."
Midfielder Rosicky has scored twice in his last three games, and has 19 goals in 156 appearances for the club since moving to England from Borussia Dortmund in 2006.
His time at the club has been blighted by injuries, including an 18-month spell on the sidelines with a rare tendon injury.
However, he has been relatively injury free this season, allowing him to make 28 appearances so far.
"I've always been a big admirer of Tomas' abilities and am delighted he's chosen to commit his future to the club," said Gunners' boss Arsene Wenger.
"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."
