Who's the last guy? Moura I presume.
Walcott went for 9-10m in the end after the tribubal ruling.
Moura is comparable due to the high end/record proce paid but he had 3 seasons (70+ games) and was widely known and chased, the other although played a similar amount of games, went for far less than a record fee. Pato had aleady played and scored at the world cup, He was the proverbial wonderkid of Brazilian football at the time.
I think its a combination that Martial was just 'not on the radar' and record fee, has created a perfect storm of 'who the/what the.. "
