Who is in and out of British teams' European squads

Cole Palmer, Marcus Rashford and Rodri are among those included in squads for the knockout stage of the three European competitions, for which clubs can register a maximum of three new players

Aston Villa have left out new signings Donyell Malen and Andres Garcia from their Champions League squad, manager Unai Emery has said.

On-loan trio Marcus Rashford, Marco Asensio and Axel Disasi are included in the side as Villa wait to find out their last-16 opponents.

Uefa only allows clubs to register a maximum of three new players to their knockout-stage squad from the league-phase roster for the European competitions.

Chelsea have added Cole Palmer to their Conference League squad after the England attacking midfielder was not involved in the league phase because of "workload management".

Manchester City, who face holders Real Madrid in the knockout-phase play-offs of the Champions League, have kept injured Rodri in their list.

Not a good decision I had to take - Emery

Donyell Malen helped Borussia Dortmund reach the Champions League final last season

Emery was left to make a tough call after signing five players during the winter transfer window and the Spaniard has dropped two permanent signings in favour of three loanees.

Netherlands forward Malen joined Villa for £19m from Borussia Dortmund last month, while 21-year-old full-back Garcia signed from Levante for a reported fee of £6m.

Villa also signed Manchester United forward Rashford on loan with an option to buy, while Paris St-Germain midfielder Asensio and Chelsea defender Disasi arrived on deadline day.

"We can only register three changes and we did more changes in the window than we wanted," Emery said.

"Even though we lost one player from the list, Jaden [Philogene, who joined Ipswich Town] was a club-trained player, so we lost the opportunity through him to have one more.

"The decision we had to take, Garcia and Malen are out. It was not a good decision I had to take but I spoke with Andres and Donyell to tell them the decision."

Villa could face Malen's former club Dortmund, Atalanta, Sporting or Club Brugge in the Champions League last 16.

Palmer back for Chelsea; Rodri keeps place

Cole Palmer has scored 14 goals in the Premier League this season

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.
