Two Bayer Leverkusen players have been criticised by their director of sport for squabbling over who gets to keep Barcelona star Lionel Messi's shirt.
"What the pair did was a bit over the top," said Rudi Voeller.
Michal Kadlec and Manuel Friedrich pursued Messi at half-time and full-time during their Champions League clash on Wednesday night.
Kadlec reportedly exchanged shirts with Messi at half-time, only for Friedrich to take it off him.
Determined not to be outdone, Kadlec, who scored Leverkusen's only goal in the 3-1 defeat, then exchanged shirts again after the final whistle.
Voeller told German newspaper Bild that he was disappointed with the way the two players handled themselves when "90% of the team was fully concentrated on the game."
Ahead of the second leg of their last 16 tie in Barcelona, Voeller added: "I can guarantee that Kadlec and Friedrich will auction off their Messi shirts for a good cause. I have not spoken to the pair yet, but I will do."
After the game, Kadlec was unrepentant about his behaviour.
"When you play against such a player, then you always want his shirt," he told Sky television.
"I would have swapped it immediately for a better result, but it is a shame that we did not do enough."
