Liverpool manager Jurgen Klopp has confirmed that striker Divock Origi has undergone surgery on a knee injury.
The Belgium international has scored four goals in all competitions for the Reds this season but has not played since December 26, when he suffered a hamstring injury against Leicester City.
Klopp revealed Liverpool opted to use his recovery time to clear up another problem the 20-year-old had, with his first-team return still targeted for February.
"It was not really surgery, it was a clean-up of his knee," said the former Borussia Dortmund boss.
"It was a little thing to do and we thought it was a good moment to do it – not the best of course, but because of his other injury we took the time.
"Now he is back [at Melwood] and everything is okay. He is on time and hopefully we can use him in a few weeks."
Klopp is encouraged to see Liverpool's injury crisis starting to ease ahead of Wednesday's crunch Premier League clash with Arsenal.
He added: "The rest are looking better, fitness-wise. All of the other guys trained.
"Divock could not train, but we had Mama [Mamadou Sakho] in training and he looked good. We had Millie [James Milner] in training and he looked good. Hendo [Jordan Henderson] in training, very good.
"Our options are now more than they were a few days ago. Hopefully we can build a good squad [for the Arsenal game]."
