Lol. The two players couldn't literally be anymore different. What Mbappe has done at his age is unbelievable and IMO far surpasses anything I have seen Martial do before or during his move to United.
I've been hearing a lot of people go on about how much of a risk he is but I genuinely don't see it. The kid is lightening in a bottle, if he doesn't turn into one of the best strikers in the world it would be terribly surprising.
It's like watching Neymar when he was in Brazil, yes, he was playing at a poor level of competitive football but you'd have to be blind to not see his obvious, unquestionable talent and potential. So the fact that we've seen Mbappe produce the goods in the CL - the highest level of competitive football - it honestly baffles me how some people don't see the necessity in this transfer.
