Mangala MK2? Really? That is a poor shout.
I watched this lad on a regular basis when Sarri was manager of Napoli and i think he is brilliant. I really do.
Its just the same as Liverpool going out and paying big money for Van Dijk. People will say its a gamble, but i don't think so. He knows how to play in a possession based side, he is excellent bringing the ball out of defence and he has the physical capabilities of adapting to this league very quickly.
He is the best defender in the market along with De Ligt at this moment in time. I hope the rumours are true because this lad could be the difference between winning and not winning the CL next season. I rate him that highly.
