#3 Philippe Coutinho

When Barcelona paid a club record fee for Philippe Coutinho in January 2018, they were expecting to sign a player who had shown much promise at Liverpool and believed he would be the long-term replacement for Andres Iniesta in midfield.
The Brazilian international started well enough to lay credence to this school of thought, scoring 10 goals and creating 5 assists from 22 matches to help the club win the domestic double despite only having a half season with the Catalans.
However, the 26-year-old has failed to build on from that and was arguably the most underperforming Barcelona player in the just-concluded season.
The former Liverpool man scored just 11 goals from 53 matches for Barcelona in 2018/2019 and looked a player short of confidence and was the subject of numerous boos by the Nou Camp faithful.
Coutinho is seemingly fed up with the situation and has reportedly demanded a transfer out of the club.
If he is to depart Nou Camp less than two years after his celebrated arrival, he would have no shortage of suitors with PSG, Manchester United and Liverpool all said to be interested.
