Casemiro only needed the answers to three questions before he decided to join Manchester United in the summer, according to reports.
The Brazilian midfielder's £60m move to Old Trafford in August was met with scepticism by some fans as they wondered whether the transfer was purely motivated by money.
The switch certainly raised a few eyebrows given that it came just three months after Casemiro had won his fifth Champions League with Real Madrid. Leaving the European champions to move to a club that would be playing in the Europa League seemed like a strange choice to some onlookers.
