Maurizio Sarri’s future at Chelsea has been put under the spotlight after their dire 6-0 defeat to Manchester City on Sunday afternoon.
Gone are the days of the unbeaten run at the beginning of the season that went for 18 games in all competitions, as the Blues have now lost six in their last 14 Premier League games.
It is quite the turnaround for the Blues and their form and Sarri has gone from being someone who could revolutionise the way that Chelsea play to one that some fans have already turned against.
But what have been the mistakes that Sarri has made that have not gone down well with fans?
Lack of rotation
With the Blues in the Europa League, it was expected that Sarri would heavily rotate his players in the competition so that they would remain fresh during key parts of the season.
But in the opening match of that competition, away in PAOK on September 20, it was clear that Sarri was not man to shuffle his pack all that much.
Kepa Arrizabalaga, Marcos Alonso, Antonio Rudiger, Jorginho, Ross Barkley, N’Golo Kante, Alvaro Morata, Willian and Pedro all started the game, with only the back-ups of Davide Zappacosta and Andreas Christensen getting their chance.
It was a decision that prompted Gary Cahill after the game to say that he wanted out of the club in search of more first team football.
Sarri has continued with a strong side through almost all of the competitions, rotating towards the back-end of the Europa League when qualification was already wrapped up.
It comes from Sarri’s belief that he should be working with a core group of players, but sometimes that just doesn’t work and that is being proved as the season goes on.
No change in formation
One of the big talking points has been the position of N’Golo Kante and the fact that one of the best defensive midfielders in the world is now playing in a more attacking role on the right.
Seeing Kante out on the wing just doesn’t seem correct and fans are starting to want to see the World Cup winner back in his role in the middle of the park.
There have been some benefits to the Frenchman playing in that position, with the high press working against teams during the campaign.
But the lack of a Plan B has not gone down well with supporters and the feeling that a 4-2-3-1 could work well, freeing up Jorginho and Kante protecting the back four more.
However, Sarri hasn’t gone with that option, or anything else away from 4-3-3, and it has become a frustration for many.
Faith in out of form players
It goes hand in hand with the rotation issues, but Sarri has given some players a lot more of a chance to play then their form would have warranted.
The prime example of that is Marcos Alonso, who has looked like a shell of the player in the left-back position that he did when he was a wing-back.
Emerson Palmieri has started just one Premier League game this season, which has stumped many supporters.
Jorginho has also been constantly backed by Sarri, and the Blues players have been given chance after chance without the performances to back it up.
Lack of belief in youth
This comes with the rest of the selection issues, but the fact that the Blues have had two talented teenagers in their ranks rarely used that has come to frustrate Blues fans.
Hudson-Odoi has made four Premier League appearances off the bench, but no starts, having been in the first XI for two Europa League matches and once in the Carabao Cup.
Meanwhile, Ampadu has seen even less time with two appearances in the Europa League and two in the FA Cup. You can’t say that the youth players should be playing every game, but you would expect them to have seen more playing time.
With the Blues looking to keep hold of Hudson-Odoi as well with Bayern Munich sniffing around, it wouldn’t be the worst thing to give him a go in the season run-in.
Training on matchdays
This is something of a strange one and not something that a lot of managers do, but if the Blues have an evening match then Sarri is known to make the players train in the morning of the game.
While it is down to last-minute preparations, football.london understand it is also down to a superstition that the Italian boss has.
To be fair to Sarri, preparation for matches on the training pitch have been in short supply due the vast number of midweek games that they have had.
However, training on matchdays is not something that goes down well with the players and could be responsible for some of their poor performances.
