For a second time, Cristiano Ronaldo has reportedly tested positive for Covid-19

Portugal star Ronaldo was sent home from international duty last week having tested positive for the virus.

He returned to Turin for quarantine though Portuguese outlet Correio da Manha now claim Ronaldo has again returned a positive reading when taking another test.

Ronaldo had missed Portugal’s clash with Sweden and was also absent as Juventus got their Champions League campaign running with a win at Dynamo Kiev.

And he is now set to miss more action with the former Manchester United star likely to have to stay in isolation for at least ten days after he returns a negative test.

Ronaldo is making sure he stays in good condition while quarantining as he was seen on Instagram on an exercise bike.

The ex-Real Madrid man also showed off a new haircut, appearing to have shaved his head while in quarantine.

Ronaldo had initially tested positive on October 13 with UEFA regulations saying he must return a negative result at least a week before a match to compete.

It puts his reunion with Barcelona star and former La Liga rival Lionel Messi in major doubt with the two having been set to meet next week in the Champions League.
