Newcastle watching Andreas Christensen's situation at Barcelona.
Sport says Barcelona need to sell to balance the books and lower their salary limit. The idea is to do this without affecting the competitive level of the team.
Barca expect offers to arrive for Christensen and the big danger could come from Newcastle, who boast an unlimited transfer budget this summer.
Barca's idea with Christensen is to keep him, and they may even look to renew his deal next season. But an offer bigger than his market rate could change the story.
The player, through his people, has advised that he is very happy at the club and has no intention of leaving.
