Chelsea midfielder Carney Chukwuemeka is expected to join German club Borussia Dortmund on loan for the remainder of the season.
The 21-year-old joined Chelsea from Aston Villa in a £20m deal in 2022.
Chukwuemeka’s game time under Enzo Maresca has been limited this season, with the midfielder making just five appearances for the Blues.
The German transfer window closes at 17:00 GMT on Monday, six hours before the English transfer window ends.
Dortmund have a well-trodden path of signing promising young English players, going back to Jadon Sancho and Jude Bellingham.
This season, England U21 winger Jamie Gittens has excelled with the club.
Dortmund are 11th in the Bundesliga and sacked head coach Nuri Sahin last month.
Niko Kovac, the former Bayern Munich manager, has since signed an 18-month deal with the club to replace Sahin.
Dortmund are through to the Champions League knockout play-offs, where they will face Portuguese side Sporting.
Meanwhile, St Etienne midfielder Mathis Amougou is set to join Chelsea for a fee of about £12m.
The 19-year-old is considered an exciting talent for the future but will also boost Maresca’s midfield options if Chukwuemeka leaves on loan.
Midfielder Cesare Casadei has already joined Torino on a permanent £12.5m deal.
Amougou has made 18 of his 19 senior appearances this season and is a France Under-20 international.
Chelsea are part of a multi-club structure with Ligue 1 Strasbourg, which could serve as a place for Amougou to develop in future seasons.
Elsewhere, Premier League strugglers Ipswich Town have agreed a deal with Chelsea to sign England U18 defender Somto Boniface.
The full-back has agreed personal terms with Kieran McKenna’s side and will join the Tractor Boys on a permanent basis.
