Arsenal midfielder Tomas Rosicky has admitted that the lack of opportunities he was given in the second half of the season has left him frustrated.
Rosicky was repeatedly linked with a move away from North London in the January transfer window before Arsenal took advantage of the option to extend his contract for another season.
The 34-year-old was often left out of the matchday squads by Arsene Wenger after the extension was confirmed and he has refused to rule out leaving this summer.
"Since the moment Arsene Wenger used the option in my contract, I haven't even been on the bench," he told reporters. "I am laughing but it´s not funny.
"It´s frustrating but I am a professional. Even if you lose your place, you must still be prepared because the situation can change.
"I'll start the summer preparation with Arsenal and that's the whole of my plan for the time being."
Rosicky started in just five of his 15 Premier League appearances this season.
