Arsenal manager Arsene Wenger is "absolutely adamant" midfielder Tomas Rosicky will stay with the Gunners when his contract expires at the end of the season.
The Czech replaced club record signing Mesut Ozil, suffering from a thigh injury, last weekend and scored title-chasing Arsenal's third goal ina 4-1 Premier League win over Sunderland at the Emirates Stadium.
Rosicky, 34, joined Arsenal from Borussia Dortmund in 2006, but has seen his time with the north London club hampered by a string of injuries.
However, Wenger said Monday: "Tomas Rosicky will stay. We have an agreement with him and it will come out soon.
"I am absolutely adamant he has to stay at the club," the Frenchman added.
"He always makes things happen, not with individual dribbling but with individual acceleration of his passing and of his runs.
"When he arrived here he was less a tactical player and more the 'Mozart from Prague' and he was purely a creative, offensive player.
"Today he is a real organiser on the pitch as well. I like to have him in the team because he gives a real structure to our team."
