#2 Adrien Rabiot (Paris Saint-Germain)

Adrien Rabiot is a 23-year-old central midfielder who currently plays for Paris Saint-Germain in Ligue 1. He has also represented France's national side, having made 6 appearances for them since his debut back in November 2016.
Rabiot is set to become a free agent in the summer after failing to agree with PSG on terms regarding a new contract. This, naturally, has turned the heads of top clubs around the world, who are now all vying for his signature. But, what will make the difference is what the clubs can offer him.
Manchester City can offer both Premier League football and wild sums of money, which is the ideal combination for a player the calibre of Rabiot. It will be difficult for any rival team to compete with the wages City could offer him.
Adrien Rabiot ticks all the boxes for Manchester City: he's affordable, given the fact he's free; and he would fit into the side well, potentially replacing the lacklustre Fernandinho in a defensive midfielder role. This is a golden opportunity for the City to improve their squad without breaking the bank.
