Everyone knew how important that goal was regarding the title race as if they drew then they would have been far too behind and perhaps even being out of it hence i dont see why his celebration was bad if you look at the context of it.
Not really, the really important goal was Morata's, as it gave them hope they can win the game again. In any case, being behind by 5 points at this stage is just as bad as being behind by 7 points.
If we do our jobs on the 27th, that goal wouldn't matter a jot as it'll take a monumental fuckup from us and Atletico for them to climb back into the race. This season they're not chasing one but two very strong teams, and both teams have had harder fixtures than Madrid and are looking far stronger than they have at any point this season.
The funny thing is their run of tough games hasn't even started yet, that starts with Juventus on the 22nd.
