Schalke have omitted Mladen Krstajic and Ivan Rakitic from their squad for Tuesday’s decisive Champions League clash with Rosenborg after they were spotted in a Duisburg nightclub in the early hours on Sunday.
Team mate Jermaine Jones, who was with them in the club but is suspended for Tuesday’s match, has been fined.
Schalke must beat Rosenborg on Tuesday in Group B to qualify for the knockout stages of the Champions League.
“The behaviour of the players is absolutely unacceptable,” coach Mirko Slomka said. “They know how they should prepare for a game … and the rules have been broken in a massive way.”
Serb Krstajic, 33, is one of Schalke’s most experienced defenders. Rakitic, a 19-year-old midfielder from Croatia, has played in all five of Schalke’s group games so far.
