If we’re discussing his market value then I’d say around £5-6m sounds about right for him.
£8-10m and you’re talking the best central midfielders in the division - the Fulham lads last year, Will Hughes a couple of years ago etc.
He’s very good and a rare commodity given his left foot. However, he’s never dominated games at the top of the division whether on form, or not and I feel would struggle in a 4-4-2 as he lacks the required qualities at both ends of the field; defending, goal scoring, physicality etc.
His value to us, in what we’re trying to achieve this season far outweighs the £4m on the table and outweighs the £7-8m we could possibly hope to achieve for him. It’s January, replacements aren’t readily available. This would set us back considerably. I’d be hugely disappointed if we choose to sell right now and I’m sure Wilder would be too if his hand was forced.
