I don't know enough about the lad to give anopinion either way on that but buying Robinson back seems counter productive to me.
As opposed to what? Jamaal lewis for £20mill, another LB for £10-£15mill to play backup to Digne? Matt Cash, another Championship fullback is being touted with a £18mill move, these are the prices floating around.
If we were going to pay £8-10mill then I'd be inclined to agree with you but its apparently £1.5mill, which could be even less if Wigan owe us money. Branthwaite, a League 2 player with about 10 appearances cost us £1mill. Its pittance for a ready made backup
