Tottenham are reportedly close to agreeing a deal to sign former Chelsea midfielder Conor Gallagher from Atletico Madrid.
The Athletic say Spurs are nearing an agreement for a deal worth €40m to sign the 25-year-old.
Aston Villa were also in talks over a deal for Gallagher, who has spent 18 months at Atletico Madrid but has found game time more difficult to come by of late.
But Gallagher is expected to fly to London for a medical ahead of his move to Spurs.
The Villains have, however, added another youngster in 17-year-old striker Brian Madjo, who joins from Metz for an undisclosed fee.
His arrival follows the addition of 19-year-old winger Alysson from Gremio earlier in the window.
But forward Donyell Malen could leave the club, with Sky Sports reporting that Roma have expressed an interest in the Dutchman.
Elsewhere, the Guardian say West Ham midfielder Lucas Paqueta is keen to leave the club and join former side Flamengo this month.
The Brazilian was left out of the squad for the FA Cup third round clash with QPR on Sunday.
The Independent, meanwhile, report that Manchester City are intent on signing Marc Guehi from Crystal Palace this January.
Guehi is out of contract with Palace at the end of the season and also has interest from Arsenal, Liverpool, Bayern Munich, Barcelona and Real Madrid.
But City are said to want to bring in the central defender earlier than that, amid several injuries in defence.
