4. Kingsley Coman (Juventus, On-Loan At Bayern Munich)
Only 19-years-old, Kingsley Coman has already played for the first teams of PSG, Juventus, and Bayern Munich. He joined the Bavarian giants on loan in the summer, with an option of a permanent deal, and has already impressed and, importantly, earned the trust of Guardiola. A permanent move to Bayern may be in doubt with Guardiola set to leave, and if that is the case then it'd be no surprise to see City swoop him and bring him to England, which would make the forward line at Guardiola's disposal even more exciting, especially as he'd offer more than someone like Jesus Navas.
