I think it's hard to argue that he isn't our best player, so, for once I can understand a refusal of what is likely a mammoth deal. He is absolutely correct in that he should be the highest paid player at the club, as PSG, Juventus, or maybe Barcelona would probably pay him more to go there and he'd have a better chance at European glory and domestic success at the moment. I do think we're a bit lucky though that Real Madrid looked elsewhere, Bayern have Neuer, Barcelona have a keeper that suits them and while there's the likelihood of more trophies, I'm not convinced PSG or Juventus are that much of an upgrade on us? He will obviously sign a deal when the offer is improved.
90% of business deals are not agreed upon with the first offer. It's always low-balled to see what they can get away with, at least to some degree. This is just obviously major news and blown out of proportion because it's Manchester United. Nothing new here, deal signed next month.
