In my time supporting I would say GTF from Udders. I think we got him for £100k, what a great deal. I would also say Paul Simpson at the time he was signed.
Nice to see the Brazilian manager has been following Critchley and is utilising some of his superb tactics, like taking a goal kick using an outfield player and passing it across the 6 yard box to his keeper who boots it out. We are so lucky to have such an exciting progressive manager!
