A statement from European football's governing body confirmed the 36-year-old has been punished for "improper conduct at the doping control" following the first leg of their last-16 encounter with Real Madrid earlier this month.

Kahn was also fined 20,000 Swiss francs (£8,400) while his Bayern team-mate Lucio was handed a fine of 10,000 Swiss francs (£4,200) for a similar offence.

Both players can appeal against the punishments.
