Coronavirus continues to take the world by storm and has now made its way into Anfield.

Xherdan Shaqiri becomes the third Liverpool player to test positive for COVID-19 in the past week.

Thiago Alcantara was the first Red to return a positive test, with the Spaniard arriving from Bayern Munich in the transfer window.

Days later Senegal superstar Sadio Mane also returned a positive test and was force to isolate and did not play in the 7-2 loss to Aston Villa on Sunday.

All three players could potentially return to the field to face Everton in the Merseyside derby on October 17, however, the protocols require all three players to go through a quarantine period of 10 days.

The 28-year-old had travelled to link up with the Switzerland squad on Monday before contracting the virus.

The Swiss Football Association on Tuesday revealed Shaqiri returned a positive test and will now undergo a period of self-isolation.

“Xherdan Shaqiri has tested positive for Covid-19. In consultation with the health authorities, he is in isolation,” a statement read.

“The strict protective measures and requirements of UEFA for national teams in accordance with the ‘UEFA Return to Play Protocol’ have been strictly adhered to since the move began.

“Based on this, clarifications are currently underway with the local health authorities about how to proceed.”

Mane however displayed minor symptoms of the virus but feels in good health overall, a Liverpool statement read.

As for Thiago, he was the first player to test positive back on Sept 30.

“It is the choice of each individual whether they reveal publicly the outcome of a COVID-19 test.” First-team doctor Jim Moxon said

“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.”

In his debut for Liverpool, Thiago had 75 successful passes, the most by any player to have played a maximum of 45 minutes in a Premier League match.
