Laliga leaders Real Madrid will be without the services of midfielder Luka Modric for their Wednesday clash against Athletic Club Bilbao due to Covid-19.
Modric is just one of the many players who will miss the tie with manager Carlo Ancelotti confirming that they will be without Rodrygo, Marco Asensio, Gareth Bale, Marcelo and Andriy Lunin after all tested positive for the virus last week; Isco being the latest case confirmed by the club on Monday.
Apart from Covid, Madrid will be without defender Dani Carvajal through injury, while midfielder Casemiro is suspended after five yellow-card bookings.
"It's true that we are missing a lot of players and maybe we will have to consider a change in the system... I don't know... I'm thinking about it.
"The system that we currently play with (4-3-3) has given us a lot in recent games. But we don't have a right-winger available, and that's the only thing that could make me change it to a 4-4-2. I have to wait for the night," Ancelotti said on his Tuesday presser.
Real Madrid's momentum - a 10-game winning streak in all competitions - ended with a disappointing 0-0 draw at home to lowly Cadiz on Sunday but are still six points clear of second-placed Sevilla, who have a game in hand and host struggling Barcelona on Tuesday.
