Ronaldinho was gutting, and ultimately cost Kenyon his job.
Essien to Chelsea, he would have won the Ballon D'or if it wasn't for that knee injury.
Hazard to Chelsea, seems like we courted him for a while and in the end he decided to go to Chelsea after they won the CL.
Not really one we missed out on but Tevez to City was annoying because he offered something different than Berbatov who was probably 4th choice during that time.
Modric and Bale, who we'd all have probably swapped for both Berbatov and Carrick if given the opportunity.
Gascoigne would have been a great player under Fergie.
Pretty sure we missed out on Silva, Kompany and Aguero due to Glazernomics and allowed City to get a grip on the league.
Kroos, who the feck knows what Moyes, LVG or whoever the feck it was that canceled this move.
De Ligt would have been a great signing, especially in our team now.
Benzema when he was leaving Lyon. I remember Fergie waiting for him after the CL game with a signed United shirt and everything.
Some I'm glad we missed out on:
Jon Obi Mikel
Fabregas (from Barca)
