Arsène Wenger expects Jens Lehmann's future to be resolved this weekend.
The German goalkeeper is mulling over a move to Borussia Dortmund, the club he left Arsenal for in the summer of 2003. The Bundesliga outfit can offer Lehmann the first-team football he craves ahead of this summer's European Championships.
Wenger insists he will not stand in Lehmann's way if he decides to leave, but he believes the 38-year-old's experience would be a valuable asset if he stayed at Emirates Stadium.
"Lehmann will be on the bench [against Birmingham]," confirmed Wenger at his pre-match press conference on Friday. "I don't expect anything to happen today. I think he has told me he will make up his mind over the weekend.
"The indication I can give is that I am happy if he stays
because he is a guarantee and he is an important player in the
squad like Gilberto.
"We have such a young squad that these players have a big weight in the dressing room and a big input in the team. I am happy if they stay."
