Its a very bad deal for these reasons.
Digne cost to us is:
Book Price: 7.2 mill
Amort: 1.2. mil
Wages: 6.2 mill
Annual cost: 7.4 mill
So we clear 17.8 million from the deal, and a cost of 7.4 mill from the accounts (however we have taken on the cost of the two new full backs)
The question is the squad stronger or weaker with Digne in it - to my mind stronger in it.
Secondly where are you going to find a better quality player then him for 17.8 mill transfer fee at an annual cost of 7.4 million - your not. Thats what people mean by the deal has to improve the squad/club - this doesn't do it.
Therefore a poor deal.
As for age 30 year old Chris Wood, is signing for Newcastle for the same fee - Digne is an infinitely more high quality player than Wood, pound for pound regardless of positions.
Bad deal and we are weaker for it.
