Chelsea, who are eyeing the Conference League title, have strengthened their squad with the addition of Palmer.

Trevoh Chalobah, who was recalled from his loan at Crystal Palace, and deadline-day signing Mathis Amougou are the two others registered by the Blues.

However, manager Enzo Maresca has seen five players from his European squad leave in January, meaning the Italian will only have 23 players at his disposal during the knockout phase.

January signings Abdukodir Khusanov, Omar Marmoush and Nico Gonzalez are the additions to Manchester City boss Pep Guardiola’s Champions League squad.

Rodri, who was ruled out for the season in September after rupturing his anterior cruciate ligament (ACL), has kept his place in the 23-man list.

Scottish champions Celtic will have Portuguese winger Jota and Jeffrey Schlupp, on loan from Crystal Palace, available for selection as they face Bayern Munich in the Champions League play-offs on 12 and 18 February.

Tottenham have added defender Djed Spence and new signings Mathys Tel and Kevin Danso to their Europa League squad, but new goalkeeper Antonin Kinsky has been left out.

Spurs manager Ange Postecoglou has dropped goalkeeper Fraser Forster, centre-back Radu Dragusin and forward Timo Werner for the knockout stage.

Ruben Amorim has named Patrick Dorgu and Ayden Heaven in Manchester United’s Europa League roster as Antony, Rashford and Tyrell Malacia were removed after their exits.

Rangers, who are also in the Europa League last 16, have added Ianis Hagi, Danilo and Clinton Nsiala to their European squad in place of Neraysho Kasanwirjo, Oscar Cortes and Kieran Dowell, who has joined Birmingham City on loan.
