Video: Pep Guardiola involved in furious tunnel row with Nigel de Jong over dangerous tackle
Pep Guardiola was involved in a furious row with AC Milan midfielder Nigel de Jong during Tuesday's Audi Cup tie.
Guardiola was enraged by a tackle from the former Manchester City player which left Joshua Kimmich unable to continue.
De Jong was not booked for the challenge, and Guardiola could not contain his anger at half-time when the players left the field for the interval.
The former Barcelona manager was seen arguing with De Jong in the tunnel, with footage of the row being recorded by German television.
Guardiola explained his outburst after the match, which Bayern won 3-0.
"I was sad for Joshua Kimmich," Guardiola said. "He can't play in the next game [on Wednesday]. He is a top player on my team and one of the best German players of the next decade."
David Alaba came on to replace Kimmich and said afterward that De Jong deserved a yellow card for the tackle.
"The challenge against Kimmich should have been punished more severely," he said on ZDF televsion. "The ball was clearly gone. Nigel De Jong rushed fully through."
AC Milan coach Sinisa Mihajlovic criticised Guardiola for confronting his player.
"Football isn't dancing and fouls are part of the sport," he said. "This is also why games like this cannot be called friendlies.
"In any case, it was one-way traffic because of how good our opponents were. They are solid and road-tested, while we didn't put in any intensity.
"We've got to improve and we are working to improve."
