The former Borussia Dortmund boss also states that Salah is available, so there's a chance that the 67-cap Egypt worldwide could feature.
But following Liverpool 3-0 thumping win over Leicester, Klopp has now claimed that the Liverpool top scorer has been cleared to join the training and he is likely to involve in training ahead of their tie against Atalanta.
"Yes, Salah's COVID-19 swab was negative".
Khaled Meghehed, a spokesman for the health ministry, told local media: "Salah's latest test has yielded a negative result".
Salah was absent from his team's confrontation against Leicester City, and it is expected that he will not participate against Atalanta in the Champions League before becoming available after that. He arrived in the United Kingdom with proper restriction ahead of the Leicester tie with a hope to recover from it prior, but the results came positive.
He said: "Am I negative?"
Salah's return comes as a major boost to Klopp who has been hit by an injury crisis in recent weeks, with the likes of Virgil van Dijk, Joe Gomez and Trent Alexander-Arnold sidelined for the champions.
Klopp also confirmed that midfielder Naby Keita, who sustained a hamstring injury against Leicester, will not be playing in the upcoming matches. The club now sees all of Thiago, Gomez, Trent Alexander-Arnold, Virgil and Henderson stay out of the game due to prevalent injury issues.
"I think it is hard to do it the first time, but it is harder to do it for the second time and even harder to do it for the third time", said Salah.
"He can train with us tomorrow". We have to be ready again. "We did well at Atalanta, but we need to do well again otherwise we will have problems", he added.
