Bayern Munich coach Louis van Gaal on Thursday ordered some of his squad to train separately after a mystery stomach bug struck down a number of the Bavarian club's players.
"We have a virus in the dressing room," the 58-year-old Dutchman said. "It's bad for us...we expect more cases within the coming weeks," he added.
As a precautionary measure, van Gaal told the infected players to train away from the rest of the first team. It comes as the German giants gear up to face Italian side Fiorentina in the UEFA Champions League next Wednesday.
Bayern were already missing five players in their German Cup quarter-final on Wednesday against second division Fuerth including defender Daniel van Buyten and goalkeeper Joerg Butt. Both, however, are expected to recover in time for the game against Borussia Dortmund on Saturday as the Munich club chase their ninth straight league win.
