TRANSFER GOSSIP COLUMN: Atletico Madrid ‘make approach to sign Mason Greenwood’… as Manchester United could let Raphael Varane leave in January and Tottenham ‘reach verbal agreement’ for Genoa defender

With less than a day until the January transfer window, clubs across the Premier League and across Europe are preparing for a busy month of negotiations.

Manchester United are reportedly willing to listen to offers for Raphael Varane in January and could offload Mason Greenwood permanently as they look to raise money for new signings.

Elsewhere, Ange Postecoglou has turned a Serie A star into one of his key signings as he looks to strengthen his defensive options, which have been decimated by injuries this season.

Spurs are also keeping tabs on one of the most in-form strikers in the Premier League, while Kalvin Phillips' move to Juventus may not be as easy as expected.

Below, Mailsport looks at the transfer rumors on Sunday morning.
