I feel a bit embarrassed that we are spending that much on a back-up RB. And despite it not working out in Madrid. Is by all accounts a highly rated talent.
If we sign Mendy and Bertrand as well. We will have spent about 150m on FB's this season.
I don't think that you should look at him as just a backup right-back. He is extremely versatile in that he can play at left-back and probably also as a CDM. Bear in mind that Fernando looks to be on his way out. Danilo could function as backup/rotation at both fullback positions and CDM. He'd get plenty of game time and it would be significantly less expensive than signing three individual "backup" players. This could pave the way for a *big money* signing like Mbappe or Neymar. I don't believe for one second that City will just watch Neymar walk toward PSG without putting up an almighty fight.
