Real Madrid may have to make do without head coach Carlo Ancelotti for Wednesday's Champions League tie at Chelsea.

Less than a year since their semi-final showdown in last year's competition, the two European giants will square off at the last-eight stage.

The first leg will take place at Stamford Bridge later this week, Ancelotti theoretically in line to return to a club where he has previously won a Premier League title.

However, according to AS, the Italian is still testing positive for coronavirus, which kept him away from the dugout against Celta Vigo on Saturday.

While the situation may change over the next 24 hours, Ancelotti may not be in a position to travel with the rest of the squad.

Carlo's son Davide Ancelotti is on standby to deputise for a second time in four days if at least one negative test is not recorded.
