As ever. some people way overreact when we lose a football game. It's not the end of the world, Liverpool were always going to pick up the title this season.
As for the game itself, City were the better team and Chelsea were very fortunate with their first goal, which changed the complexion of the game. We were actually growing in cofidence at that stage of the first half, started bright, lost a bit of composure after Chelsea started showing their countering threat, then we started getting control of the game again, and they were looking more and more penned in. That's how Mendy and Gundo ended up casually giving the ball away on the half way line. The mix up highlighted the lack of a consistent lineup and that Mendy isn't quite fully confident in himself yet. I for one can understand why considering his last 3 seasons, Gundo should have recognised this and taken charge. I know that seems as though Gundo is being made the scape goat but I do think KDB or Fernandinho would have spotted Mendy's body language straight away and done just that.
In the second half, we had to take it to Chelsea more and commit more to attack, which played into Chelsea's hands. We played our best football that half, which would have been enough against most teams but Chelsea had a lot to play for and have a better and larger squad than most teams(we were never going to just brush them aside). They were obviously fresher than City last night, since we've played more games, which played it's part in the last 20 mins or so. After KDBs goal, we needed Sterling to square that ball to Mahrez for an easy finish and that would have finished Chelsea off IMO. Their heads would have dropped at that point and we'd have just passed them to death for a bit but it wasn't to be. When Laporte came off, Abraham's fresh lanky legs really showed the lack of pace at the back, just a simple long ball over the top as we pushed for a a goal at the other end, was causing all sorts of problems... that ball wouldn't have been on had we gone ahead though.
I think the game at least showed us, we are not quite up to speed in defence and attack(to a lesser degree), plenty to work on for the games ahead that actually matter. Jesus not starting, is not some big mistake. Some people are just asking for an injury to our only available out and out striker. Thinking he can just come back and play every 3 days, after the biggest break from football most players have ever had, is a tad naive in my opinion.
