A spokesperson cited confidentiality as the club refused to confirm or deny the information, but the club have made it clear that their plans remain unchanged.
They will train in the camp, in the mountain retreat on the outskirts of Salzburg, for the remainder of the week, before continuing their short pre-season with warm-up matches ahead of the Community Shield against Arsenal at Wembley on the 29th. August.
The Reds are completely cut off from the public in their camp, after taking over a hotel. The players underwent tests for Covid-19 before leaving for camp on Saturday, upon arrival in Austria, and at regular intervals throughout the week.
A test was positive, but a follow-up test will be done to rule out a false positive, before a case is confirmed.
Liverpool have strict protocol to follow in their pre-season. Players stay in a bubble away from the public, and are tested every two or three days. If there are positive tests, the infected person is immediately placed in isolation.
If a second test is positive, then the individual will be kept away from the team for at least seven days, and until the test produces a negative result.
Will Liverpool defend their title? Comments below
Club officials said the camp was unaffected by the situation, with players continuing to train through contact, and mingling after sessions, at the restaurant and hotel where they are in a full bubble.
This isn’t the first minor drama the club have seen in the preseason.
They were due to travel to a camp in Evian, their usual location for the start of preseason training, but the British government imposed a quarantine requirement on all travelers from France, which forced the Reds to change destination in Austria at short notice.
The club, however, remains relaxed about the situation and the protocol is in place to deal with any positive cases of coronavirus.
