1. Ivan Rakitic
Ivan Rakitic played a crucial part in Barcelona's LaLiga title run last season as he featured in 35 games for the club. He is still an integral part of Ernesto Valverde's plans as he has featured 29 times this season already for Barcelona in all competitions.
Now 30, it may be time for Rakitic to take a bit part role given the arrival of youth or leave the club. It will be better for him to leave rather than being fringed out of the squad as he is too good of a player to be left out.
With a club like PSG missing out on Frenkie, they may go on to get Rakitic to fill the void which will be left by Rabiot, who has allegedly expressed his desire to leave and henceforth not renewed his contract with the club.
