Veteran goalkeeper Oliver Kahn has told rival Jens Lehmann he must leave Arsenal if he wants to start for Germany in next year's Euro 2008 finals.
The two outspoken goalkeepers have not always seen eye-to-eye during a long-running battle to be number one in the German national team.
But Bayern Munich keeper Kahn has now turned up the heat by suggesting Lehmann must quit the Gunners if he still harbours hopes of playing in next summer's finals.
Lehmann has not featured for the Premier League leaders since August and is now back-up to new number one Manuel Almunia.
"Jens Lehmann's services to the national team have been impeccable, but you can't play in a European Championship when you are not in the team," Khan told German media.
"That's why it would be best for him to go and play where he will be in the team."
Lehmann, 38, has hinted he would be interested in a move back to the Bundesliga in January in a bid to keep his international dream alive.
Wolfsburg are believed to be interested in securing the services of the former Borussia Dortmund keeper.
