you're all assuming that the Glazers will go in the summer "oh shit, we had a tough time last season Davey so here's £100m".
I don't think they will, even if they get 4th they provision for 3rd and the knockout stages of the CL, they'd be a playoff away with that.
I reckon they will sell Rooney in the summer to cover the cost of Mata going and then Moyes will get £50m tops, and the way he and Woodward are showing they do business I'd be confident selling clubs will take the piss out of them.
Unless they appoint a proper DoF and the Glazers have a change of heart about how they want to run the club Chelsea are doing good business, selling a player for a lot of money they don't want and replacing him with a cheaper, younger player they do want, and putting money back on the books particularly after splurging on the likes of Willian in the summer, it's money that can go in the kitty for a top CB and striker in the summer.
If United make top 4 bar 1 position they'll have met their targets for this season, the Glazers don't care about winning the trophies they just want the extra revenue of the top 4 and CL.
