Leaving refereeing shitshows and really this entire game aside, I think when we look back at this season in a few months we'll realise that we were just spread a bit too thin. Not now necessarily, but over Christmas and January and it caught up about a month ago.
De Bruyne, Fernandinho, Otamendi, Walker...they've all played too much football this season and have all lost form for the last month to 6 weeks. Sané and Sterling also look a little off it and I wonder if it's mental fatigue with those two as much as anything. Bad luck with some absences too, Mendy and Silva's long time off can't be predicated for. The management obviously thought Yaya would feature a lot this season too after the way he ended 16/17 but that went out of the window early doors.
We're going to get 2 more players in the summer, maybe a 3rd in Maffeo, and I suspect that will make a monumental difference at the end of the season, just being able to rest and rotate throughout Christmas.
For now, we've got Spurs followed by 5 straight forward league games in which to cement this sides place in Premier League history. The points, goals and wins records are all within pretty easy reach. A league and cup double is a fantastic season, the most successful season in the club's history when you factor in the dominance in the league.
