I think his potential is extremely high really. Never truly know how some players will develop - he's outperforming Ronaldo at the same age for example. Does that mean I think he'll be more than half the player Cristiano has been in his career? No. But even being half as good, he would be a top class player! He's 19, his decision making isn't always the best. That's where his inconsistency lies, but he has pace and determination. He always runs at players which is something I want in a United wide man. I think he will be a better player than Rashford personally, maybe not score quite as many goals in his career, but still an overall better player. He gets kicked as much as anyone but always gets up and goes again. He's developing really well. Probably ahead of schedule - we need to sign a couple of attacking players so we can share the minutes around.
The major difference at the moment is that Mainoo, Garnacho, and Hojlund are coming into a team where they're probably the stars and we have that expectation of them. Whereas Ronaldo, Rooney, Class of 92 etc were all coming into an established top side with brilliant pros to turn to in the tough games/situations. I hope we sign a few players of that ilk in their mid-to-late 20's this Summer.
Unfortunately, I think he'll get his first true big contract with us in 2-3 years time and then after 5~ years he will probably be coerced by Real Madrid and we'll sell him for over £100m
