Being perfectly honest I don't think Cafu is good at anything. Not really a progressive passer and certainly isn't good at defensive duels. Zero goals so far.
I would say his best strength is driving forward with the ball but more often than not he gets the ball taken off him.
He would be OK in my works 5 aside team but ask him to last more than an hour on a half sized pitch seems beyond him.
I thought he looked really good when I first seen him but he flatters to deceive which is a pity coz I really wanted him to turn out to be a gem of a player.
