There are reports Miralem Pjanic has a fever, so could be benched for Juventus against Atletico Madrid, while Joao Cancelo is heading for right-back.
The first leg in the Champions League Round of 16 kicks off at 20.00 GMT.
According to Sky Sport Italia, Pjanic woke up with a slight fever and will remain in doubt until the last minute.
It’d be a blow for Juve, who already lost Sami Khedira for a month due to heart surgery.
Meanwhile, it is also rumoured that Cancelo will be chosen rather than Mattia De Sciglio at right-back, but that too remains up in the air.
Atletico Madrid seem to be dropping hints that Diego Costa will start in attack rather than Alvaro Morata, as his image was used in the tweet publicising this evening’s game.
Atletico Madrid: Oblak; Juanfran, Gimenez, Godin, Filipe Luis; Saul Niguez, Thomas, Rodri, Koke; Morata/Diego Costa, Griezmann
Juventus: Szczesny; Cancelo/De Sciglio, Bonucci, Chiellini, Alex Sandro; Bentancur, Pjanic/Emre Can, Matuidi; Dybala, Mandzukic, Ronaldo
