Former Manchester United star Marouane Fellaini has tested positive for the coronavirus, he said Sunday, becoming the first known case in the ­Chinese Super League (CSL).

The 32-year-old Belgian international midfielder, who recently returned to his CSL team Shandong Luneng, wrote on Twitter, "Thanks to the fans, medical staff and the club for their care and attention.

"I will follow the treatment and hope to return to the game as soon as possible. Please everyone stay safe," he ­added, posting a picture of himself smiling and giving a thumbs up.

Shandong Luneng said Fellaini had a normal temperature and was feeling fine, but "is under observation and having treatment at a designated medical facility."

"The club will do its best... to help in the treatment and recovery of the player."

Fellaini is the latest high-profile name in football to catch the disease, along with Juventus forward ­P­aulo ­Dybala, Chelsea winger Callum Hudson-­Odoi and Arsenal manager Mikel Arteta.

Former Real Madrid president ­Lorenzo Sanz, who was hospitalized with the coronavirus, died on Saturday at the age of 76.

But Fellaini is the first confirmed case in the CSL, dealing a blow to the league's hopes of starting the season as early as next month. 

The campaign was supposed to begin last month but has been ­indefinitely postponed by the outbreak.

Fellaini, also formerly of Everton, joined Shandong Luneng from Manchester United in February last year for a reported 7.2 million euros ($7.72 million).

Officials will be taking a close look at Fellaini's recent travel history to see who he had contact with.

Having flown from Singapore to Shanghai, he reportedly took a high-speed train from there early on Friday to Jinan, the city home to Shandong Luneng.

He was taken by car to a quarantine area and tested for the virus on Saturday, media said.

Also on Saturday, the Chinese Football Association said the country's best-known player, forward Wu Lei, had also tested positive for the coronavirus.

Wu, who plays for Spanish strugglers Espanyol, is in self-isolation at home in Barcelona and has only mild symptoms.

"Dear fans, as you might already know I indeed have got the virus," said the striker.

"Now I'm at home in self-quarantine. Mentally, I'm very well and my symptoms have almost all gone," he added in a video on Twitter-like Weibo.
