Frank Lampard described Marouane Fellaini’s ‘headbutt’ on Sergio Aguero as a moment of madness having been booked just seconds before.
The 174th meeting between City and United burst into life six minutes from time when Fellaini saw red following a heated altercation with Aguero, just seconds after being booked.
Lampard, speaking on Sky Sports, insists he would have kept a low profile, and said Fellaini's team-mates deserve an apology.
"He gives away a solid yellow card, and he deserves it. It's then about eight seconds until he commits another one, and that may not be a yellow.
"If I'm Fellaini I'm thinking: 'How do I get out of this, act innocent?' And then bang, headbutt.
"He needs to go to his team-mates, who he left to defend for 10 minutes with 10 men, and apologise to them in the dressing room. It's madness, he compounds it with a certain red card."
