Listen, sometimes in life you make mistakes and go on paths that are not good for you. If you are lucky, you got strong people caring about you in form of family and friends. They can help you with good advice and be there for you.
I do believe Rashford got people who care for him, but I am pretty sure he don’t get advice that contradicts his own opinions. And imo, he needs at least one family member or friend he cares about to challenge his opinion and give him some good advice.
All in all. People have different goals in life. Some wants to be the best in what they're doing like Ronaldo. Rashford goals might be set for life, financially, I don't blame him. Most play football for the financial aspect, nothing wrong with it.
And as much as we think he's been I'll advised by those around him, in his eyes they could have done a marvelous job landing 300k per week and set him up for life. Earning megabucks 99.99% footballers can only dream of. By the time the contract ends he's 30 and solid financially he doesnt have to kick a ball ever again.
Fans sees football as some sort of holy crusade, giving your all and bleed for the team, talking about privilege, pride, but hey it's just a job for some.
Could he have knuckled down, relinquish his lifestyle, maintain the my body is a temple and play till he's 35 at high level? Maybe, but why would he if money is his goals. He got that contract and unless he stupidly do stupid things like Punching Amorim or going Awol that contract is as good as guaranteed.
If money is his goals. He really has no incentive to try hard and worked his ass off everyday. He had made it money wise, why bother with so much trouble. The pays are the same, it's not like he can work hard and become as good as Messi and earns 600k per week. It's real life.
I dont blame him for having this thought, we're all humans. But dont blame me for calling it as it is, a player who's not worth keeping and should be sent packing. Hey it's business, nothing personal. It goes both ways.
If United is bottom league table, we dont begrudge good players that wants to step up and offered a better offer, so dont begrudge United for wanting a better player who cost much less salary wise.
