Ok, so we all know we had Eric Dier and let him go etc
But who are the other players we had and let go only to rue it in years to come?
Straight away Richard Dunne comes to mind, fella coulda been an Everton legend, that was a big mistake.
Looking at the state of our defence right now, I am starting to think Shane Duffy also could prove to be a big mistake. Saw him for Ireland last night and he was a colossus.
ps - Michael Ball/Franny ETC dont count, I am sure you "get" what I mean by let go
Wasn't Dier on loan from Sporting Lisbon?
