Manchester United offered the asking price, and offered the wages he wanted iirc.
He started sprouting on about how unfair he'd was being treated ect ect...
He then ran away to the richest club in the world, who agreed to pay him lots and lots of money.
Kaka might not of being Robinho all over again, money isn't everything to all footballers. Just a shame you can't offer them a better standard of football and have to rely on picking up mercs who play for money.
Remember they could OFFER Tevez whatever contract they wanted, he was their player at the time and they weren't breaking rules talking to another player, the players owners didn't accept any offer, why would they accept 25mil for Tevez when City were offering FAR FAR more.
I've yet to see anyone at Utd claim they had an offer accepted for Tevez, and it doesn't matter what they agreed with Tevez or what contract Tevez was willing to accept.
Take pretty much any example, Arsenal could accept 5 offers for, RVP, 3 at 10mil, 2 at 12mil, the clubs agree terms with RVP and the player doesn't care where he goes, the person who signs on the dotted line gets to choose which club he goes to, that would be Arsenal, they can choose to accept the best, or the most convinient.
Agreeing a wage with the player, honestly, means nothing at all.
I have a hard time believing that Kia accepted a 25mil offer when supposedly City paid 35 or 45mil for him.
Ade wanted more money and had clearly tried to negotiate a move out of Arsenal the previous year, but was apparently upset Milan weren't willing to pay him a massively higher wage, then Arsenal, inteligently, rewarded him with more cash.
