I like Diallo, and he obviously has a future ahead of him in the top flight, be it at United or somewhere else.
There is, however, a great deal of goal/assist bias with him, as well as Twitter highlights bias, which is normal, since most United fans have barely watched him play for 90 minutes, as they don't watch Sunderland matches.
Although he has racked up a very commendable goal points tally for Sunderland, his overall game still needs lots of improving.
He could do with being more press resistant, an even better passer, better presser, and so on. Although he has good player ratings throughout the season, a lot of that is goal bias. It happens a lot with players who are quite average in games, but then nicks a goal or scores a worldie. They'll get an 8/10, whereas their overall performance was more like a 6/10. This happens frequently with Rashford, as a perfect example.
If you regularly watch Amad for 90 minutes, it's very obvious that he is still a far cry from being good enough to warrant a start in a team looking to fight for the biggest trophies.
And with the talent he has, he still has 2-3 years to hit that level.
I suspect he won't be at United in 2-3 years. He seems really good, and certainly much better than Elanga. He has a fantastic precision shot on him, that is undeniable!
But, from the full matches I've watched, I am not overly impressed with his overall play. It's good, but I don't think it will be quite good enough for what we need, and how we will be looking to evolve under ten Hag.
