Salah was ruled out of Egypt’s Africa Cup of Nations qualifiers against Togo during this month’s international break having contracted COVID-19 while in his native country.
This also saw him miss Liverpool’s 3-0 victory over Leicester on Sunday, though he had already flown back to the UK along with Arsenal‘s Mohamed Elneny, as the two clubs fronted the cost for a return under secure measures.
The No. 11 underwent his fourth COVID-19 test ahead of kickoff at Anfield, and thankfully is no longer positive, allowing him to return to training.
Klopp confirmed this in his post-match press conference, with Salah now an option for the Champions League clash with Atalanta on Wednesday night provided he passes a UEFA test on Monday.
It is a major boost for the Reds, with Klopp likely to be planning changes for the visit of the Serie A side considering it comes less than 72 hours after full-time in the Premier League.
A trip to Brighton then follows within a similarly short timeframe on Saturday, with Liverpool needing to rely upon the depth of their squad despite a number of injuries.
