Newcastle United have been linked with re-igniting their interest in Bafetimbi Gomis.
Gomis was a summer signing from Lyon, snapped up by Swansea on a free transfer, but did not feature against Newcastle in the weekend's 2-2 draw.
The Sun on Sunday report Newcastle want to sign the Frenchman, despite missing out on him in the summer.
"They will pay the fixed release fee in his contract, believed to be £7 million."
Gomis has yet to score a Premier League goal for Swansea this season, making two starts and three substitute appearances, behind Wilfried Bony in the pecking order at the Liberty Stadium.
The clause in his contract means Swansea can't stop Gomis leaving for Newcastle if that is what he wants, and much may depend on the trajectory of the two sides in January.
Newcastle sit in the relegation zone at present, while Swansea are fifth in the Premier League.
Both Swansea and Newcastle face losing strikers to the African Nations Cup in January, Wilfried Bony and Papiss Cisse, and so the battle for Gomis' services could intensify.
Newcastle themselves lost Demba Ba in similar circumstances two January's ago when Chelsea met his £7 million release clause.
The Mail reported only in June that Gomis was 'poised' to sign with Newcastle, with Mike Ashley negotiating with the player's representatives, only for him to choose Swansea instead.
If they did go back for Gomis, they would have to see him step it up in the Premier League during the rest of the calendar year.
