You're using bizarre examples to show that Fergie was great at nurturing lazy players... Anderson, Veron and Berbatov... All of which were flops. Fergie was absolutely awful at nurturing lazy players, almost certainly because he felt that if you couldn't be motivated to put the effort in for the biggest club in the world then you were a somewhat lost cause. He'd give you every chance to grow out of that youthful laziness but fundamentally you'd be on the bench if you didn't put your body on the line physically every week.
I keep mentioning Pogba because he was a very talented player who never got an opportunity under Fergie because he wasn't committed enough to showcase his talent at the level he was playing. His complacence/laziness lead to him not performing for the reserves, which lead to him never getting an opportunity in the first team. Of course Fergie wanted to keep him, he was very talented and at 18 the manager would have hoped he'd grow up. Fergie would also hope to keep Martial for the same reason, however he wouldn't be trusting him in important games because of the fear that his laziness would let the team down. He'd almost certainly have opted for a less talented but more trusted player such as Park, Young, Valencia, Fletcher or even Welbeck.
Fergie and Mourinho are exceptionally alike in this sense. Work ethic was the key attribute in the spine of both managers teams and philosophies.
