4) Nemanja Matic
Another Serb who has gone from hero to zero at Chelsea. Nemanja Matic.
The powerhouse midfielder was a rock for the Blues last season in their title-winning campaign, but so far this season, he’s been invisible and has gone missing.
His partnership with Cesc Fabregas has broken down completely and because of that, Chelsea’s midfield has been a disaster.
From one of the best players in the Premier League, to a walking disaster in a matter of months.
