Liverpool defender Nathaniel Clyne could be out for up to three months after having surgery on a back injury. Klopp had earlier said on Clyne's injury, "Nathaniel is working hard on his rehab and we have kept a close eye on his progress, but the reality is we are looking at some time still before he is back and available for selection".
Clyne's injury forced the German manager to omit him from the Merseyside club's Champions League squad group stages. Clyne has always been struggling with the back problem, which has seen him miss all competitive fixtures this season. He returned to training a few weeks ago, but suffered a set back in his recovery. Hot on the heels of returning to action in the 4-1 win over West Ham United, the 25-year played his part as Senegal qualified for their first World Cup in 18-years - an outing that left his long-term fitness in question.
Liverpool's head of medicine Andy Massey travelled with Clyne to London after deciding the surgery was the best option.
Joe Gomez and Trent Alexander-Arnold have been deployed at right-back by Klopp in his absence while Tottenham's Kieran Trippier has been favoured by Gareth Southgate in the England set-up.
On Monday, news also spread that Sadio Mane had returned to Liverpool after his recent hamstring injury flared up again while on worldwide duty with Senegal.
