Bayern Munich manager Pep Guardiola has claimed Juventus are "too big of a club to complain" about a disallowed goal in the German champs' 4-2 come-from-behind defeat of Juventus.

Juventus director Beppe Marotta slammed match officials for disallowing what appeared to be a legitimate Alvaro Morata goal in the first half of his side's Champions League-ending defeat at Bayern Munich on Wednesday.

Morata looked to have put Juventus 2-0 up in the 23rd minute after a mis-kick from Bayern goalkeeper Manuel Neuer bounced off Sami Khedira and onto the feet of Morata, who was all alone in the box.

Despite successfully chipping Neuer, the Spain international was adjudged to have been offsides. But upon further review, he appeared to be in a legal position.

Speaking to reporters after the match, Marotta said the call changed the match, which eliminated the 2015 finalists from the competition.

"The Alvaro Morata disallowed goal would've changed the face of the match. Certain errors at this level are costly, they make a big difference," Marotta told Mediaset Premium.

"I am not here to seek alibis, but I hope that in future Italian football is better protected. Certain refereeing performances are painful.

Upon hearing of Marotta's comments, Guardiola shot back, telling reporters the complaints were beneath a club of Juventus' stature.

"Juventus are too big a club to complain about this," Guardiola said after the match. "When you lose, you shake hands and go home. You compliment the opposition.

"They had chances and scored twice. Perhaps the goal was not offside, but these things happen in football."
