lol @ the negativity.
I think this is a great signing and I think it's great work done by the board.
Is Grimaldo even a starter at Benfica? How many games did he start in the league and CL since he signed for them. Give me one solid argument for him being better than a 22 years old player who at this young age plays every game for a pretty good team like Roma.
PSG is no authority on the value of players. This guy could be the real deal soon and PSG might look dumb two years down the line for letting him go.
20m. is not a lot of money for a promising LB who at 22 was a starter at AS Roma. And the Italian league is not as easy as some make it out to be.
