Forward Roberto Firmino has given Liverpool a Champions League final boost by returning to training.
The Brazil international has missed the last three matches with a thigh problem but was able to take part in the first session of the squad's pre-final camp in Marbella.
Firmino was the first player to arrive on the south coast of Spain having attended slightly earlier than his team-mates for some individual sessions with strength and rehabilitation staff.
Liverpool said his reintroduction into full team training "will be carefully managed under their supervision, with specialised programmes planned over the coming days".
The 26-man squad is spending six days in Marbella before returning to England to finalise preparations for their June 1 meeting with Tottenham in Madrid.
Included in that group is Naby Keita, who continues his rehabilitation from a serious groin problem suffered almost three weeks ago and is not in contention for the final.
Defender Trent Alexander-Arnold has the chance to set a new record if he is selected in the XI to face Tottenham in Madrid.
Should that happen the 20-year-old will become the first player aged under 21 to start consecutive finals in Europe's premier club competition.
The previous youngest was AC Milan's Christian Panucci with AC Milan in 1994 and 1995.
Mohamed Salah will miss the second leg of Liverpool's Champions League semi-final with Barcelona due to a concussion.
The Egypt forward suffered a head injury in Saturday's win over Newcastle and manager Jurgen Klopp said at his pre-Barca press conference he would not make the Anfield clash.
"It's a concussion so it's a case of him not even being allowed to play," said Klopp, whose side are 3-0 down after last week's first leg in Spain.
"He feels OK but it's not good enough from a medical point view, that's all."
Klopp had already conceded Salah's fellow forward, Roberto Firmino, would miss out with a muscle problem.
Liverpool have it all to do to turn around the tie on Tuesday and Klopp knows the loss of two of his most lethal weapons does not help the cause.
"There's hope and that's football," he added. "We are far away from giving up.
"Two of the world's best strikers are not available tomorrow - it doesn't make life any easier but while we have 11 players on the pitch we will try."
Roberto Firmino trained on Tuesday as Liverpool undertook final preparations before flying to Barcelona for the Champions League semi-final first leg at the Nou Camp.
The Brazil forward missed last Friday's Premier League defeat of Huddersfield with what manager Jurgen Klopp described as a "small muscle tear".
Midfielder Fabinho, who was not risked against Huddersfield after a blow to the head in the previous game, was also involved as the Reds held an open session at their Melwood training complex ahead of Wednesday's game.
