The club reported on Tuesday that Liverpool midfielder Thiago Alcantara has tested positive for coronavirus and is self-isolating.
The 29-year-old Spaniard just joined Bayern Munich's Liverpool last month in a move worth up to £ 25 m, and made his Premier League champions debut on September 20 in a 2-0 victory at Chelsea.
He was a surprising absentee from the Liverpool squad that faced Arsenal in a 3-1 win on Monday night, but his absence has now been clarified.
Liverpool issued a statement announcing his diagnosis via the club's official Twitter account: "Thiago Alcantara has tested COVID-19 positive and is now self-isolating according to the required guidelines."
"The 29-year-old, who missed the match against Arsenal on Monday, has shown mild virus symptoms but is in good health and is getting better."
"All measures related to COVID-19 have been and will continue to be implemented by the club and Thiago will remain in self-isolation for the appropriate time span."

LFC first-team doctor, Dr Jim Moxon, added: “It is the choice of each individual whether they reveal publicly the outcome of a COVID-19 test.

“We have followed all the protocols to the letter and Thiago is OK. He will be self-isolating now as per the guidelines and hopefully he’ll be back with us soon.”
