Jens Lehmann is investigating at least one offer to leave Arsenal.
The Germany goalkeeper has languished on the bench at Arsenal this season due to injuries and some poor performances, while Spain's Manuel Almunia has established himself as the starting choice for the Premier League leader.
"I should know more in a week, so that I can make a decision in the first days of the new year," Lehmann was quoted as saying in Berlin daily Tagesspiegel on Sunday. "I've listened to something, but at the moment I can't say much about it."
Lehmann said he believes Bundesliga club VfL Wolfsburg _ which has publicly expressed its interest _ has contacted Arsenal manager Arsene Wenger.
The 38-year-old Lehmann also said he would be interested in a switch inside the Premier League to Manchester City.
"But I haven't spoken to anybody there," Lehmann said of City.
Lehmann runs the risk of losing his starting place for Germany ahead of the 2008 European Championship if he doesn't regularly play topflight soccer.
The chances of regaining his starting job at Arsenal seem to be dwindling. On Saturday, Almunia saved a penalty kick in a 2-1 win against Tottenham.
Lehmann said his aim at Arsenal this season was to reach the Champions League final again, making amends for the 2006 final when his 18th-minute ejection paved the way for FC Barcelona's 2-1 win.
"But slowly I'm starting to ask myself if another Champions League final is going to happen again for me," Lehmann said.
