I’m not sure that’s true. Everyone always think of Evra and Vidic where that definitely happened (more so for Evra than Vidic, who only really had a handful of ropy games) but we signed them a very long time ago. Can you think of anyone we signed in the last 15 years who had a poor start and subsequently became a key players for us? Or anyone before Evra/Vidic who fits that description?
Depressingly, we’re much more likely to see new signings have a good start before ending up as not good enough than we are to see the opposite!
