Could this have been handled better by the club? Sure. We never should have offered him an extension in the first place. But now that we did, I'm happy the club seems to have offered him wages that match his recent performances. He has been stealing a living for years.
Personally, I couldn't care less that we backed down from our initial offer. This is a negotiation. Nothing wrong with adjusting our offer when his performances drop.
Let's stipulate that De Gea is trash and that he stole a living off us for the last decade and that we must get rid of him if we're to have any hope of progressing the ball up the pitch.
Are you really ok a business enterprise making a firm offer to a contractor or employee and then only after the contractor or employee signs the contract offer that the business enterprise offered it or him to withdraw that offer?
Fukkinell what a world we live in if the answer is now yes, that that it is a perfectly respectable business practice.
Had the second party rejected the offer by the first party, the first party is well within its rights to revise the offer -- either up or down -- as happens every minute of every day. But while an offer from the first party is pending and the second party accepts the offer, in writing, it is disgusting business practice for the first party to retract its own offer.
A meaningful distinction could be made if the offer was contingent on external conditions being met and were in fact not met. For example, an offer could and often does include a time clause -- valid for only 7 days or whatever -- and if the second party doesn't accept the offer within that 7 day period of time then the offer has expired and the two parties are essentially starting from scratch. This may well have been the case here -- that United offered an offer that was valid until a certain date and if De Gea signed the offer after that date then the first party has clean hands.
But we neither know that that was the case or not the case, but if is the case that De Gea had before him an offer from the club that met all the conditions set forth in the offer itself -- it must be signed at Old Trafford, for example, and the expiration date of the offer was June 30, and he signed that contract offer, as presented to him, it is shitbaggery in the extreme by the club to retract its offer after it was signed pursuant to the terms that the contract offer specified.
