No rental fees, no purchase option – improves better and better.
Next year, he will return, with an even lower market value and will again ask for a salary increase …
Are you serious ?? Do you have a better ready offer? Will its market value on the bench or on the stands improve in United? Why are you boring about the missing purchase option? Why should United pay him an increase in salary? Questions about questions ….
There were supposedly better offers and not, of course not, so a permanent departure would be better and that is why I am also bored by the gone ko. And not united should pay him a salary increase, but, as also written, he demands (!) First of all. He did it after all wages were reduced due to missed international competition, as contractually agreed.
Thus, all your questions do not exist if you deal with the subject.
If you mean a purchase obligation, I would agree with you, but not with an option.
A purchase option is advantageous for the potential buyer, not for the seller. If I define a sum X as a purchase option and the player presents himself so well that different clubs say that we would pay (clearly) more) more than X, but that the potential buyer really buys the player, then you have made a higher income. If the player does not play well enough for the sum X to be considered justified, but you can imagine additional cooperation in more than better terms, then the potential buyer will negotiate anyway. And if you are not lucky, they don’t even offer you a cheaper purchase, but another loan. If you are interested in the potential buyer, the purchase option can be negotiated freely, in all directions, which restricts the purchase option.
When I said that United did not have to pay a salary increase in Onana, it was linked to the case that if Onana in demand, United has no need to take it. Each employee can request an increase in salary and each employer has the right to reject this …
And it is not because the media talk about all the offers that offers exist. Why should United also reject better offers?
