I don't actually understand that.
But anyhow, if Sanchez wants to come to City, he can do, it's upto him.
If he doesn't want to & prefers the money on offer at Utd, he can fuck off & in that case I'm glad, because we only want players who are committed to City & we could have had one who isn't.
To recap: Sanchez can sign for City, if he wants to. Exactly as planned, no change. And if he does, it proves he really wants to play for us, so all good.
Someone else quoted you and said the same, there could be many scenarios but one being we would happily part with a transfer fee, signing on fee and chunky wages over a "promise" in the summer is madness if we then don't even want him.
