Cheers bud. In modern market, £30m is cheap for a solid tier 2/3 (CL class) midfielder. Guys like Kroos, will be double that. This summer, I would say we need 2 full backs, an out and out wing wizard in addition to the midfield purchases. I think we'd have the budget to get three midfielders.
If we are losing Fellaini, Carrick and possibly Perreira and Herrera stays in poor form, not to mention Matic a season older and at risk of burnout, same with Pogba.. we need numbers next year and can't afford to penny pinch in the engine room. Two mids at the very minimum, three is possibly asking for abit much but that is why I think we should go all out for Wilshere on a free. Even 10 games a season for a guy of that calibre would help us in say cup games, odd CL game, some league games. Iniesta is also available on a free.. so maybe we can seek out a bargain for a third midfielder just to give the squad some depth.
