I did say i wasnt going to post any more on it, but as you directed at me ill respond
I agree, but should they be able to make such an agreement in the first place? Its just a slippery road when the prem says its ok to make such deals now. Legally there is nothing anybody can say, as there is nothing signed. Its mostly from a sporting fairness (however much of that there is still left is another matter) point of view that it could cause problems.
What the main consequence could have been for everton is a poor relationship with manu regarding future transfers.
But again thats speculation. And its between them anyway.
Ill use the eto example to turn it around and make another.
Say its this time next year:
Manu have eto, but they have a verbal agreement not play him against barce this season. During the past 2 months they have been negotiating a transfer for a left sided winger, as a replacement for giggs who is getting a bit on, everything has been agreed, player fee, contracts, etc and all they now have to do is wait for the transfer window to open. In 2 weeks they play each other in the CL final and a barca representative reminds manu of their agreement to not play eto, and hints that if they do they, under no circumstances, will allow the agreed transfer to go through, meaning manu have possibly wasted their time for a player over the past 2 months. Which in turn means barca can influence manu, had there never been such an agreement the transfer would have been "objective" and only about the fee and the team he's going to etc. Now though they have a certain level of control.
Which brings you to the following, is it fair for barca to be able to put manu i such a situation? And is it fair that manu have let themselves been put in such a situation? I mean they have both agreed to it, so really between them there shouldnt be a problem. But from a bigger perspective it can jeapordise (sp?) the intergrity of the final and in turn the competition.
If you placed it from another position, manu are playing barca in the final and they say: if you play rooney we wont let you sign "pablo lefty". Wouldnt everyone be up in arms at the cheek of such a demand?
Essentially its about keeping the integrity of the games, deals like this can jeopordise it. Although i also agree with your statement about there being no legal document, meaning they cant really do anything about it. But that doesnt make it correct.
