Rashford had been an issue for the past 3 past managers. Ole was one of the first to highlight issues regarding his training. Then ETH came in and there was issues with training as well + Belfast gate. Fast forward to present time and we've got issues under Amorim as well with Rashford running to Henry Winter were he said that he wanted up. Add that to months of Rashy simply jogging on the pitch and you can come to a conclusion that the guy simply doesn't want to be here.
United had been consistent as well. Ole was forced to apologize in public which is a first for a United manager while under ETH Rashford was fast tracked back to first team. Amorim gave Rashford 2 chances to retract first by claiming that Rashford's 'new challenge' was him and then by saying that he only cared about how players act in training. In both occasions Winter had come out insisting that Rashy wants out.
SAF protected the fans from the nasty parts of football in two ways. First of all he quickly removing the bad apples both at youth level (ex Djordic, Ravel and Gillespie) and at first team (ex Ince, Tevez and Heinze) before they were allowed to create drama. Secondly he constantly brought success to the club. A player who joined United for let's say 200k a week, with another 50k tied to performance bonuses (ex trophies won) + a 25% decrease if we don't make it to top 4, knew that he would walk out with 250k a week, year in year out. That wasn't necessarily the case with the likes of Inter, Liverpool or Chelsea. All of that went away once SAF was gone. We lost that father figure who could anticipate problems before they hatched and the club lost its route to success which in turn made bonuses difficult to hit and it made it normal for players to suffer salary cuts. Someone whose in football to make money (like 99% of players are) wouldn't like that.
I think that United fans need to grow up. Most players sees football as a job, they want to make the most £££ out of their career and have no particular love towards their employee. Its common for players to leave clubs, kick a fuss and even join rivals if they make financial sense. Roberto Baggio for example played for Fiorentina, Juventus (Fiorentina's most hated club), Milan (Juve biggest rival for trophies) and Inter (Milan's biggest rival). It would be equivalent to Cantona leaving Everton to join Liverpool then join United and finally ending with City. Hence why I only judge players on what they produce. If they are not worth their while then they should be kicked out irrespective whether they are local/foreign and the many excuses they might bring to the table to justify their failure. United is a football club not a mental clinic, a nursing home, a charity or a hospital. That's ain't personal, just business.
