Liverpool were dealt a big blow during their Club World Cup final win over Flamengo as Alex Oxlade-Chamberlain sustained a worrying ankle injury.
The midfielder found it hard to influence the game before he sustained an ankle injury midway through the second half.
Oxlade-Chamberlain fell to the ground after an awkward landing and was in visible agony as he clutched his right leg, eventually hobbling off the pitch in a worrying sign for all in red.
He was seen on crutches and with a protective boot around his ankle after the game, much like Fabinho who suffered a similar injury last month.
Speaking after the game, Klopp said: "Hopefully it is not too serious. Even he was smiling at the end which helped us all.
"When he’s landing, he gets a kick. He feels OK, so we will see.
"It is of course not perfect, but we will have to see if it is a ligament stretched only or ruptured, partially or not."
The hope will be that it is just a minor muscle tweak rather than anything more sinister, with the England international having already suffered his fair share of injuries during his career.
The full extent of Oxlade-Chamberlain’s injury is expected to be known late on Sunday evening, with the squad returning to Melwood earlier in the day.
