#1 Neymar (Paris Saint-Germain)

Paris Saint-Germain spent a whopping amount of £200 million to sign Neymar from Barcelona in the summer transfer window of 2017, making him the most expensive footballer of all time.
The Brazillian played 36 league games for the Parisiens since his move, scoring 33 goals in the process. He played a vital role in PSG's domestic treble last season and was awarded the Ligue 1 Player of the Year 2017-18 for his performacnes.
However, the former Barcelona man has struggled with injuries during the current season and has managed to play just 16 league games. He currently earns a mountainous salary as compared to his team-mates, which might make PSG cash in for him during the summer transfer window, bearing his injury record in mind.
According to the reports, Real Madrid are showing interest in signing him and that could see him on the move once again during the summer transfer window.
