Philippe Coutinho showed a glum-looking face as he arrived for Liverpool training as his team-mates prepare for their Champions League qualifier in Germany.
The Brazilian is desperate to leave for Barcelona after handing in a transfer request, but the Reds are adamant he is not for sale.
Coutinho was injured for Liverpool's Premier League opener against Watford, suffering from a back problem.
The injury has ruled him out of the Champions League play-off with Hoffenheim, but the 25-year-old has reported to the Melwood training ground as he steps up his recovery.
Joined by Daniel Sturridge, who suffered a thigh injury against Bayern Munich in the Audi Cup, Klopp will hope the pair recover soon.
The first leg at the Rhein-Neckar-Arena in Sinsheim, Baden-Wurttemberg will be pivotal to the Reds' season.
Failure to qualify for the group stage would be a disaster after squeezing into the top four last season.
