Liverpool have suffered a triple blow after Jurgen Klopp confirmed injuries to Philippe Coutinho, Roberto Firmino and Daniel Sturridge following the Reds' 2-0 win over Sunderland on Saturday (26 November).

The Brazilian midfielder was stretchered off 35 minutes into the game with an ankle injury following a challenge by Didier Ndong. The German manager was unable to give insight into the severity of the injury and is awaiting the scan result.

Coutinho's absence will be a massive blow as he is the Merseyside club's in-form player and has played a key role in helping Klopp's side mount a title challenge. They are currently in the second place on the Premier League table, just one point behind leaders Chelsea.

Firmino, meanwhile, was substituted late in the game, and Klopp admitted later that he had a minor calf problem, but was in less pain than Coutinho, who is likely set to face a spell on the sidelines. The Brazilian duo are two of the triumvirate that form Liverpool's forward line that has scored 16 of the 32 league goals this season – the third being Sadio Mane.

Sturridge, on the other hand, failed to make the squad for the game against the Black Cats after failing to train with the squad with a calf injury. Klopp was unable to give a timeline for his return only confirming that he will miss the next training session as well.

"We have to wait for the scan. What we know in this moment is it is something with the ankle and that's it, so we all have to wait," Klopp said following the 2-0 win at Anfield, as quoted on Liverpool's official site.

"He had pain, but pain gets better. In the first moment, it was obviously very painful but when I saw him at half-time, he said the pain was much better. We have to wait.

"If I have no idea what it is, how can I imagine how long it will be [out]? I am actually quite an optimistic guy – so I hope he can train tomorrow!" the German coach added about the Brazilian's injury.

"He is much better than Phil, but has pain in the calf," the manager said about Firmino.

"He [Sturridge] had a tight calf. He hasn't trained for two days and I have no idea when he is back. It is not sure that he can train tomorrow, so he was out because of this injury."
