As raz said, that win was a bit down to luck honestly but given how some games have gone this season the team deserves that luck.
Positives of the game were silva once again showing he's the only player in the team who's game is not affected by pressure, yaya rolling back the years and giving a very assured performance especially in the second half on the back of leicester pressure, sane who looked dangerous in bursts throughout and the much needed 3 points at a vital time of the season.
Negatives. The obvious one personnel-wise is clichy who really should not be anywhere near a squad with city's aspirations but i'll leave that for now and get to an even bigger issue with the team and one that Pep has a huge job on his hands next season to fix. I've frequently complained about this team and pep's game management in countless situations where the pressure has been on and momentum shifted in favour of the other side and the team totally loses all discipline and focus for spells which end up costing them points. Its happened against tottenham home, monaco away, everton away and most of the other games the team drew at home. I know many put the blame on poor defense, goalkeeping, and convertion rate which while have all played some part, they all conversely also tie in to game management which has imo been the biggest difference in the team fighting for a champions league place instead of a league title.
Now there's been games where decisions(ref), player mistakes and bad luck(woodwork) just hasn't gone for the team which has played some part but the players and Pep's ability to manage situations where the tide has been turning has left a lot to be desired. There was a moment in today's game and its happened too many times this season where the other team were clearly gaining confidence and nervousness started to creep into the ground and some of the players. Instead of them showing a bit of positional and defensive discipline in those brief periods in order to calm the tide and slowly gain composure and control back in the game, you will often find some of them(mostly the midfielders) completely vacating their position and marker to try and close down a ball that they have little or no chance of winning often leaving a gap that gets easily exploited and puts pressure on the defence. I understand Pep's thinking in always wanting the team on the front foot and applying pressure in the hope that the attackers will outscore the opponents from the errors and chances that creates, but that way of playing is not sustainable throughout a whole game and season especially with the current personnel of the team and in times where the team is under pressure. Conte instilled that kind of game management into the Juve players when he was there and seems to have done that at chelsea this season where they know what to do when faced in those situations. You can't always put the blame on players as this city team is the same one that went on to restrict the then winners real madrid with its attacking talent to just a goal(a lucky one at that) in two ties with the likes of Mangala, fernando and clichy in the side.
This doesn't mean the team reverts to becoming totally defensive, in fact you will find most of chelsea's goals have come on the break when the other side looked to be gaining momentum. It just means the players show a bit of discipline and awareness and opt for a more controlled, counter-attacking mentality in moments in games where they are under pressure and would've made the world of a difference in games this season where the team has gone on to concede cheap goals. Its clear that there needs to be a big defensive overhaul especially in the goalkeeper and full-back positions as well as an anchor man but if the team and pep continues to manage games in the manner he has for most of the season(front foot,all out attack at all times), the team will face the same problems next season regardless of who gets signed.
