Arsene Wenger insists he is not sure if goalkeeper Jens Lehmann has played his last game for Arsenal in the 2-0 FA Cup third-round victory at Burnley.
Lehmann is mulling over a switch back to his homeland
Lehmann, 38, played only his fifth match of the season for the Gunners at Turf Moor and has been linked with a return home to Borussia Dortmund.
"He had a faultless performance and was highly focused. He showed again what a great professional he is," Wenger said.
"We'd like him to stay but I've said many times, the ball is in his court."
Lehmann is tempted by the prospect of regular first-team football to boost his hopes of winning a place in Germany's Euro 2008 squad.
Wenger added: "If he decides to go I don't want to close the door for him because of the European Championship."
And Germany goalkeeping coach Andreas Kopke said on Sunday: "From a sporting point of view, it would be desirable to have him playing regularly again.
"In Dortmund, he would have plenty of opportunities in the second half of the season."
They gave us a real game and I was impressed by them
Lehmann and his team-mates, meanwhile, were given a tough time by Burnley before sealing their passage into the fourth round of the Cup.
Kyle Lafferty, who was later sent off for raising his studs in a sliding challenge on Gilberto, struck the bar early on before goals from Eduardo and Nicklas Bendtner saw off the Championship side.
"They gave us a real game, and I was impressed by them," Wenger admitted. "They missed an early header where they should have scored and it was difficult because Burnley played very well.
"But we were focused and steady and after they had the sending-off we controlled the game."
The score flattered Arsenal and on another day we could have achieved a positive result
Clarets boss Owen Coyle was full of praise for his men, who have struggled in the league of late.
"We created opportunities that probably should have resulted in goals, particularly Kyle's effort early on," he said. "Moments like that are pivotal.
"We were always in the game, we committed players forward as we said we would and gave them a stern test.
"Against Arsenal 11 v 11 is difficult at the best of times so to go down to 10 was a mountain to climb but it was a valiant effort, we still had opportunities with 10 men.
"The score flattered Arsenal and on another day we could have achieved a positive result."
