That's Wilder's MO.
Some of the best players he's signed have been free agents and been picked up from leagues below. McGoldrick is, in my mind, one of the best signings the club has ever made yet nobody wanted him when we did.
He's no good at walking into something like Middlesbrough or Watford that just needs a tweak. Its something that needs wholesale changes and rebuilding that is where Wilder excels.
What he needs to be able to do is, on the rare occasion that we do have a bit of cash to spend, is to be wise with it and learn from his mistakes because one of them is still here, still injured, still being paid and still hasn't scored a goal in about 3 years!
