I also think talent is an issue, not just mentality in terms of whether he is a £300k player. He has two genuine outstanding parts to his game in my opinion, his acceleration and his runs to break a back line from the wing if there is space. I don't believe he was ever touted as a generational type talent in the youth ranks like a Greenwood, but rather a good talent. He has carried his speed well into adulthood which has served him well. However, even when he arrived into the first team it was clear there were technical gaps (or lets say technical areas that were not that strong), mainly his link up play, play in tight spaces and finishing. Gaps that he hasn't improved that much on. He is a very inconsistent finisher, even in the 2 seasons where he has scored loads of goals he has still displayed an erratic finishing ability.
Outside of finishing, he doesn't seem to have a good small space game in terms of giving and going, intricate patterns, receiving the ball in tight areas etc. Which isn't his game but again highlights how fairly restricted to moves that exploit his pace he really is. If you take away that blistering pace he is a decent pl winger but not much more. His poor mentality just exacerbates those technical gaps. There is no way a player who is potentially world class can have such massive dips so consistently. Its getting to the point where the dips are becoming his normal form and the 2 high scoring seasons the outlier.
My theory with Rashford is the club got giddy and wanted to push him as the next big thing when in reality he was only going to develop into a good player. I belive if we build a team that challenges for premier leagues and champions leagues that Rashford is really only a bench level player in that team.
12 months ago he had just scored 30 goals in a season and registered 11 assists, and now he's worse than Antony and Pellistri.
