I think it will be madness to let Saido go to Tottering Hotspots. It would be a bad move for him, money aside, to go to a team that are going nowhere.
For us, unless the money is really exceptional - around £30+m - we lose our star player and likely replace him with ageing has beens or never wasses. We should be building a team around him, even if it is only for a year or two.
