How much time do you want him to have, he has had three years and his initial few months were far better than what he did before signing Sanchez. Lets not forget Sanchez is one of the best left wingers in the world that we signed, even though he obviously hasnt performed like it so far. I really dont think Martial is a left winger anyway, I think he can develop into a very good striker, his best spell was up front under LVG in my opinion when he first came. And you have hit the nail on the head, he wont get the oportunities with Lukaku in front of him to develop into a top striker. For that reason he is right to want to leave, and he doesnt hold so much value to us as I would put Rashford ahead of him on the left too. It is a shame as personally I dont rate Lukaku as highly as most and I do think Martial can become a top player but he hasnt done anything special consistantly here if three or four years and there are plenty of other top talents about, lets not forget France have Dembele and Coman for example of a similar age who I think are more developed and more talented. He wants to go if the press is to be believed, why on earth should we stand in his way for £60-70m considering what he has done so far?
