Auld Enuff Tae Know Better This Radge
The nearest I can offer as a comparison would maybe be Jason Holt. Busy, nippy, likes to get forward and would bolster our goal threat from Midfield. In a midfield 5, he'd be ideal, in a 4, you'd need someone alongside to bolster things up a little. He came and absolutely starred when we were at our lowest ebb in League 1. As we got better, he became a fringe player.
Without knowing what NL is looking to set us up like, I'd say he would offer something we don't currently have, but doubt he'd be NL's sort of player. I'd probably sign him, but then I like 5 across the middle.
A player that's gone backwards hugely at the Huns.
