Berlin - Morocco captain Mehdi Benatia has threatened to leave Bayern Munich if they sign fellow centre-back Mats Hummels from rivals Borussia Dortmund for next season.
Hummels, 27, has told Dortmund he wants to leave with a year left on his contract and Bayern have confirmed they are negotiating to bring the Germany star to Munich.
But Benatia, 29, is unimpressed by the prospect of having to battle wih Hummels for one of the centre-back berths at Bayern and has criticised the Bavarian giants.
"Bayern are negotiating with Hummels. If I should go, then I'll go," Benatia told Sky Italia, ahead of Tuesday's home Champions League semi-final, return leg against Atletico Madrid.
"But first of all I want to finish the season well, we can still win the treble.
"I wouldn't do what the club has done, which is to talk about transfers before a Champions League semi-final."

Benatia came off the bench in Bayern's 1-0 defeat to Atletico in the first leg in Madrid last Wednesday and has not earned a spot in Pep Guardiola's first-choice team at Bayern.
His potential future employers could be Roma, who sold him to Bayern in 2014.
"I'd definitely go back. Everyone knows that Rome is a special place for me," he added.
"So many people from there remain in my heart.
"If I should leave Bayern, Roma would be a possibility."
Bayern are set to become the first club to win four consecutive German league titles if they take at least a point at Ingolstadt on Saturday.
They will also play Dortmund in the German Cup final on May 21 in Berlin.
