No booking afaik
Should have been a booking. As should Lamela's on Fabregas. Certainly, that's what Dermot Gallagher thought. Even if some might disagree, neither was so obviously a red card offence that they will be dealt with retrospectively.
The only player who, according to the laws of the game, should unquestionably have been sent off was Fabregas for kicking out at Lamela in retaliation.
