Germany international Lukas Podolski has refused to discuss his future beyond the end of the season.
The striker is reportedly keen on a move away from Cologne, having questioned the club's ambition in recent weeks.
A move to Arsenal is believed to be in the offing, but when asked about a potential transfer the 26-year-old told reporters: "I have nothing to say."
He went on to reveal that he will give his all until the end of the season with Cologne.
"I will give all I have got to the very end," he added. "We have ten more very tough matches.
"Every game is a final for us. On Saturday we have an important game against Hertha and we need to win that game at all costs."
Podolski joined Cologne in 2009 from Bayern Munich.
