I can't see this not happening and what more I think he is good signing for them on a sporting level, would have loved him at City but one man does not make a team and the price is far too much!!
United have blown everyone out of the market by over paying on fees, wages and agent fees.
We know when he score a world class goal and he will, we'll hear that's what £100 million gets you etc. However won't we will not see is in all the contract renewals, future transfers that United will struggle to get any kind of value (there paying elite prices for someone below that level). The ego's around that place if it starts going wrong is going to be the ultimate meltdown and fun to watch!
I remember when we where in the position United are in now and had to make statement to announce ourselves as a player with the big teams with our pursuit of Kaka and would happily overpay to show teams we can attract the best players, now we are above all that and look to get quality players for the right money.
It is actually where United are now, we are so far ahead of them that they are throwing money at the problem and seeing what sticks!!
To pay £100 million for a player worth about £60 million in this insane market, who wants to go to Real and is hardly going to be thrilled with Europa football.
I don't think we need to be too worried!!
