Schalke manager Ralf Rangnick claims Max Allegri's Milan helped his side beat Inter in the Champions League on Tuesday.
The Bundesliga outfit came back from behind at San Siro to win 5-2 and look almost certain to qualify for the semi-finals of the competition.
"I did well to watch the Milan derby personally," Rangnick said. "I understood that Inter didn't press at all in midfield and left big spaces.
"They were vulnerable to quick opponents like Alex Pato and those who are capable of taking the initiative like Milan did.
"I asked my players to give everything, to attack every ball and to play with a high line to be as least far away from the Inter goal as possible."
