Below, FootballTransfers runs through the biggest rumours and gossip from 29 December, including the latest updates on Manchester United and Celtic.

Man Utd talks

Manchester United are reportedly in “serious negotiations” to sign Auxerre striker Lassine Sinayoko on a free transfer next summer.

That is according to a shock report from AfricaFoot, who claim that Man Utd officials are in talks with Sinayoko’s representatives over a Bosman deal when his current contract at Auxerre expires at the end of June.

It’s reported that Man Utd are hoping to finalise a pre-agreement with Sinayoko during the upcoming January transfer window, with the 13-time Premier League champions set to offer the Mali international an annual salary of €3 million.

Celtic agree January deal

Celtic have reached an agreement to send summer signing Hayato Inamura on loan to FC Tokyo, according to reports in Japan.

The 23-year-old has only made one first-team appearance for Celtic since his arrival in Scotland, while he has been excluded from the matchday squad in 28 of their 30 competitive fixtures in 2025-26.

As a result, he has unsurprisingly been linked with an early Celtic Park exit and the Glasgow giants have now reached a basic agreement to send the 23-year-old on loan to FC Tokyo next month, as per Japanese outlet Daily.

Chelsea want to re-sign Antonio Rudiger

Chelsea are reportedly among the clubs interested in signing Real Madrid defender Antonio Rudiger on a Bosman deal in 2026.

The Blues have pivoted their transfer strategy to signing the most talented youngsters from across world football in recent seasons, however they are among the clubs interested in finalising a deal for Rudiger next year.

That is according to Spanish publication AS, who report that Al-Hilal, Al-Nassr, Galatasaray and Paris Saint-Germain are also keeping close tabs on Rudiger’s situation at Real Madrid as they pursue a potential free transfer.

Kylian Mbappe blocks Real Madrid transfer

Real Madrid are ready to trigger the €90 million release clause included in Vitinha’s current contract with Paris Saint-Germain, but Spanish publication Defensa Central have confirmed that president Nasser Al-Khelaifi will block a possible transfer due to Kylian Mbappe.

The Frenchman famously left PSG to join Real Madrid on a Bosman deal in 2024 and Al-Khelaifi remains furious about the deal.

As a result, he reportedly has no intention of allowing Vitinha to follow in Mbappe’s footsteps and he will do “everything in his power” to stop the 25-year-old from joining the Spanish giants next year.

Chelsea have reportedly rekindled their interest in Manchester City star Oscar Bobb, but they may need to sell Pedro Neto before pursuing a deal for the Norwegian.
