I wouldn't complain if we only signed wide players this summer, that's how desperate we are (and have been for years) for width.
I'd sign Hoillet (about £6m) and Vaz Te* (if West ham don't get promoted) along with 2 top wide players like Hazard (and a.n.other widely touted wide man) for £40m.
A total spend of £50m and given that Hoillet and Vaz Te can both play as a second striker as well which creates all sorts of interesting team selections that would make us as good going forward as we are defensively.
United have Nani, Valencia, Giggs & Young as wide players and rotate regularly and we should have similar (only better options).
*It's hard to put a value on Vaz Te because West ham only paid £500,000 for him less 6 months ago BUT he is finally realising his true potential. I always thought he's go onto be a much better player than N'Zogbia, Downing, etc and finally he looks like he's got his act together. Maybe worth a £4m offer if West Ham don't go up.
