This is it exactly.
At Brighton, Potter and Ashworth (at the time) mapped out a clear route for him for development and first team football, he had a couple of appearances before he went off to our feeder club, USG, in Belgium. We knew that Bissouma was unlikely to sign a new contract and he was signed for succession.
At United there is no clear route offered and when managers change, styles of play change completely as well, so there are no guarantees, whereas when we changed from Potter to De Zerbi, the style was tweaked rather than changed dramatically.
It's difficult for big clubs who expect to win every match to take a risk like Caicedo and play him regularly, there's no room for feck ups. But the flipside is, you guys have much much more money and can afford to buy ready made pl players.
I think if Pellistri and Amad had joined Brighton (they joined United 6 months before Caicedo joined Brighton and are the same age) both would be regular and established pl players by now.
