Mino wants a clause in his next contract if that is to be believed, he has one in his Dortmund one but he promised Dortmund he would stay for 2 years which in January he has.
could do the same with his next club I’ll sign for you, for 4 to 5 years then let me have a clause for this much money etc.
Mino and Haaland are not stupid. Just think this is where football is going with players. They know clubs won’t let them leave if they want to go example of this is Kane, with a release clause that issue is gone and a player can sign for who he wants when he wants to.
The club that doesn’t want to sell might not like it, but they will get the clause fee to reinvest in player/ Players that would want to join. Example Grealish 100 million clause payed Aston Villa invested in some quality players with the money.
Gives the player more Control over his career. If he’s at a club that is not meeting his ambitions.
