If world class means they can get into almost any squad or like top 5 in their position it would be
Saka Saliba and Rice.
I’d like to think most teams would want Odegaard and Martinelli but I wouldn’t necessarily rank either top 5 in the position as of right now but they have the capacity to make it there later in their careers imo.
The world class debate in general is pretty ridiculous because everyone has different meanings.
Poor mentalities, poor financial management, poor man management, poor recruitment, leech owners.
Any manager that takes the utd job would struggle. Any success that happens will be short term success until major changes happen throughout the club from top to bottom.
