Stoke City will get a chance to bounce back from their slim defeat to Burnley FC three days ago when they welcome Liverpool FC to the Britania Stadium in Saturday's Premier League encounter.
The 24-year-old Senegal global, who has played a major part in Liverpool's bid to finish in the Premier League top four, suffered the injury in a challenge with Everton's Leighton Baines in last weekend's Merseyside derby and had his knee in a brace all week. I thought he was lucky in this situation that not more happened, but it will be pretty much impossible that he will play again this season.
Adam Lallana and Sadio Mane have arguably been Liverpool's two best players this season but while Lallana could potentially be back by the start of May, his offensive teammate has been ruled out for the remainder of the season.
They may be in a poor run of form having lost their last three on the trot, but Potters boss Mark Hughes won't be losing any sleep over the Reds coming to town.
"But then he'll have a long break and be ready for next season, so that's the only good news".
Klopp said: "Phil is still ill and was not at Melwood yesterday".
The final seven games of the season have just become a whole lot more hard for Klopp and his men.
"Sadio we are pretty sure will need surgery".
His absence comes as Klopp's men have seven matches to try and seal a return to the Champions League amid a fierce battle with the likes of Tottenham, Manchester City, Arsenal and Manchester United.
"We will have to see if we [can] bring him in tomorrow".
Yet he insisted he had no regrets and said: "Of course I would love to replace a player with exactly the same quality, maybe his twin".
'The only thing we have to forget, if you want, is that we are Liverpool and have to play like Liverpool. Both Joe Allen and Charlie Adam could keep their places in the side to square up to their former employers, but questions remain over the availability of Xherdan Shaqiri despite the enigmatic Swiss midfielder rejoining training in time to be in contention.
