We seem to have a few differing deals in place for players
Douglas Luiz - Optional buy back clause with an agreed fee
Jack Harrison - Loan with an agreed obligation for Leeds to buy.
Angelino - Loan with an agreed fee with an option to buy
Sancho - Sold with an agreed percentage of any further sell on fee
What is the best option if any?
Jack Harrison and Angelino look to have a low sale value put on them.
I have never heard that happen, only as an overage clause, not for any future fee.
When these clauses are added it normally means the club gets less than they otherwise would, so if the palyer does very well they work out in the selling club's favour but the opposite it also true.
For example selling Iheanacho for £25m with a £50m buy back would have been excellent if he turned into the beststriker in the league, however looking back getting £30m and no buy back would be prefered now as he looking about a £10m valautaion now.
There is no best option.
