Manchester United left-back Alex Telles has tested positive for coronavirus, it was confirmed on Thursday (AEDT).
Telles, who arrived at United from Porto for a reported £15.4 million (A$28 million) earlier this month, made his debut for the club in last week's UEFA Champions League win over Paris Saint-Germain.
The 27-year-old has since missed two matches, including Thursday's 5-0 thrashing of RB Leipzig at Old Trafford.
United manager Ole Gunnar Solskjaer subsequently confirmed Telles had contracted COVID-19, but was feeling fine.
"Telles has tested positive for coronavirus so he's been out for a few days," he told a news conference.
"No symptoms though, so he'll be fine. Back soon."
Top of Group H in the Champions League but 15th in the Premier League, United host Arsenal on Monday.
