To be fair I didn't even say good, I said OK. Using the West Ham as the yardstick as its the premier league and French league is hardly something you can rely on for how good players are.
Ultimately it doesn't really matter how much he costs if he is great he is great and we will all be happy but he really does need to be great to warrant a £70m price tag
I am just thinking about how Mahrez cost us £60m and the quality he had shown at Leicester vs what Paqueta has done at West Ham is very different.
