Philippe Coutinho has been filmed training on his own after reporting for international duty with Brazil.
Coutinho has not played for Liverpool this term and last featured for the club during the Audi Cup in Munich during pre-season.
Jurgen Klopp said Coutinho, who handed in a transfer request earlier this month, was not available for Reds selection - first due to a back injury, and later due to illness.
But the 25-year-old appears to have overcome those issues if the footage of him training with Brazil ahead of their forthcoming World Cup Qualifiers with Ecuador and Colombia is anything to go by.
In a video released on Twitter by the Brazilian Football Federation (CBF), the Liverpool playmaker is seen sprinting before guiding the ball into the back of the net with both feet, although he is not currently involved in full-contact training with the rest of the squad.
Coutinho missed Sunday's 4-0 Premier League demolition of Arsenal but appears to be fine now, judging by comments made by friend and Brazil national team doctor Michael Simoni.
He said: "Coutinho back problem? He is OK now. The back problem was a matter of stress, it was something emotional.
"The uncertainty about his future led to him feeling stressed. Everything is solved now.
"Coutinho and I have been friends for years. I always treat his medical cases. All he needed was someone to give him a pep talk."
Coutinho has been heavily linked with Barcelona since his compatriot Neymar left the Nou Camp for Paris Saint-Germain in a £198m world-record deal.
Barcelona have seen three bids for Coutinho - the last worth £118m including add-ons - rejected this month, but the Catalans could try and tempt Liverpool with a late offer before the transfer window slams shut.
