Southampton boss Ralph Hasenhuttl admits they risk losing Jannick Vestergaard this summer.
The Dane is now inside the final year of his current contract. Danny Ings' situation is also a concern for Hasenhuttl, who like Vestergaard is also now inside the final year of his deal at Saints.
Quoted by Bold, Hasenhuttl said: "It's getting harder and harder to extend with players these days. It can be seen. The whole system does not work as it should in my optics.
"Players can speculate about leaving clubs on a free transfer, and thus switch wherever they want.
"It is a problem for the smaller clubs, because we have paid a lot in transfer fees. For Danny Ings we paid a lot of money, and we did the same for Jannik Vestergaard."
Indeed, Hasenhuttl admits he is concerned about what such transfer laws will do long-term to the fabric of the game and it's clubs.
He also stated: "So it is quite difficult to extend with players. Times have changed and it is no longer so interesting for players to become legends in clubs.
"It's not good for football, but that's the market, and we have to play the game like other clubs."
Vestergaard's value to Southampton was confirmed in his absence last season. Saints were seventh on the Premier League table before he collected a knee injury in December and they slipped down the ladder in his absence. He also missed the 9-0 defeat by Manchester United at Old Trafford.
Fully fit for Euro 2020, Vestergaard started all six of Denmark's games as they were ultimately beaten in the semifinals by England.
