Barcelona defender Andreas Christensen is being linked with a return to England.
The Dane is in his third season with Barca, but has lost his first-choice status with the Blaugrana.
Sport says Christensen's situation has alerted major Premier League clubs.
Manchester United and Newcastle United are both in contact with Barca about Christensen.
However, any move is more likely at the end of the season, rather than January.
