Am sure he did but ultimately he only has himself to blame. Jack Wilshere also had standout performances in the CL as a youngster.
Anderson came into a strong squad that would go on to reach back to back CL finals, winning one and dominate in the PL. Blaming Fergie or United doesn't cut it am afraid.
Sometimes depends on the type of player and role that it´s asked of him. Juan Veron was a great player but failed in United for the same reason: the system was not a fit to his skills.
It made no sense to buy a Ronaldinhoesque type of player and play him as a DM.
