Bayern Munich coach Jupp Heynckes has criticised Franck Ribery for his stamp on Juventus midfielder Arturo Vidal in the Bavarians' 2-0 Champions League win over the Old Lady.
The Frenchman caught Vidal on his calf with a late lunge in Tuesday's encounter at the Allianz Arena, but escaped serious punishment as the referee opted against booking him.
Nevertheless, Heynckes was not impressed with Ribery's action and has urged him to curb his aggressive streak.
"What Franck did was completely unnecessary. He should have controlled his temper," Heynckes said at a press conference.
The Bayern boss stressed that Ribery was not the only one who crossed the line, though, as he feels Vidal played his part in the incident as well.
"The way he [Vidal] went in a few times was a bit too much, too. He crossed a line once or twice. But I knew that could happen."
Heynckes worked with Vidal at Bayer Leverkusen from 2009 until 2011.
