Allegri claimed the defeat in the US was down to a lack of concentration, but Galliani disagreed with such an assertion.
“When you play against Real Madrid, you should not think it is just a friendly,” Galliani was reported as saying.
“We’re in New York, in front of 60,000 people, a full stadium, all eyes on him, millions of eyes connected via the TV. Milan is not playing at a Serie D side.”
Galliani was apparently unhappy with Allegri making nine substitutions in the second period. Real coach Mourinho made 11 changes.
"Mourinho has made as many changes? But have you seen Real? Kaka, Higuain, Arbeloa. As many changes were not made," said Galliani.
“It was a serious mistake and I will not tolerate these figures. I’m pissed off."
