£5 million tops. How much of that is eaten up by the Hagi fee i'm not sure. Hopefully that will be covered by last/this seasons EL run. Personally i'd spunk the lot on an experienced, ball-winning midfielder who's not afraid to mix it. A cheaper version of Souness if you like. Ideally someone with experience in British football, perhaps even an old pro from the likes of Stoke, Burnley, or some other perennial mid-table EPL side.
I get that will leave us bare at LB and up front. I think we might need to free up a few more salaries (Barker, Jones, and either Stewart or Kamberi) and hopefully pick up a couple of decent loan deals to fill those holes. However, I believe we are a small step away from being a really good side, and a player like this would not only be the final piece in the jigsaw, but elevate the contribution from others in the squad. IMHO part of reason we havent seen the best of Kent is he needs a minder (so will Hagi by the way) and there are others in the side, such as Jack and Arfield, who have fire in their belly and just need a leader.
Ideally Ross McCrorie might fit this role, but I dont think he's ready and there are still reservations over his ability. However with Ross in mind for the future, that might allow us to move for an older more experience pro. We might even get one out of contract and save on the fee. However, we cant dick about on this anymore. Whether you call it lack of fight, bottle, psychology, its clear this type of player is sorely needed in our side. It's the Elephant in the Room with the gaffer's management IMHO.
