Yes, the club buying back would still need to agree terms with the player. If he doesn't want to move, he doesn't have to move, unless there is something in his contract with Saints, but I don't think that it would be lawful.
Not sure what happens in the case of the player moving to a 3rd club...
I do believe we would not agree a buy back that Saints were willing to include, whether Livramento would have chosen Brighton over Saints is moot, his choice was whether to stay at Chelsea with a new deal, or move to Saints, as the only club that had agreed terms with Chelsea.
I have just imagined Colwill slotting a pass through to Gilmour, who steps round Caicedo, and knocks it wide to Livramento, who skins Cucurella and plays it into Gallagher, who then scores past Robert Sanchez, at Stamford Bridge.
Tariq Lamptey warming up on the sidelines celebrates wildly...
Marc Cucurella was loaned to Eibar from Barcelona with a 2M euro buy option that came with a 4M euro buy back. Eibar bought him at the end of the loan, and Barca immediately bought him back and did a loan with buy option with Getafe for 6M euro, with a 40% sell on.
What it means is, if any club...
Funny bloke, crediting Lampard with giving youth players a chance, when it was only because they were under a transfer embargo, as soon as that was lifted Frank was straight into the transfer market and spending large.
