Probably only one and he'd be overvalued. I can only think of four Mauros who play football. One is too old and was shit at West Ham; one was good at Dallas but is playing millionaire football in Dubai; one plays for PSG but is on loan in Turkey and would never justify DP value; and the other was the dude you just pointed out this morning.
I think there was a Mauro who played for Brazil when I was a kid too. Might have been Portugal.
I think we need a central midfielder who's defensively capable and will challenge for a starting role.
