I used to think all our players were great in the early to mid 90's when I started going to Maine Road.
Frontzeck - Awesome - I remember editing him on some football management game to how good I thought he was and selling him for £15m or something.
Flitcroft and Lomas were the best central midfield pairing in the league of course. Obviously I liked the players who actually were quite good as well (Rosler, Curle etc).
Not read the whole thread, but credit to anyone who mentioned John Foster - he was going to be amazing until he er.. wasn't (think he did dislocate his shoulder at some point in fairness).
More recently, I liked Bianchi.
