After Chelsea’s win at Brentford in midweek, Tuchel confirmed a group of key players had returned to training after providing negative Covid results.
He said: If I understand it right, we need a negative test first of all, and we had that for Romelu [Lukaku], Callum [Hudson-Odoi] and [Ben] Chilwell today.
“Ben will not be involved in the Aston Villa game, but the other two can be on the pitch tomorrow if they test negative.
“The guys have had some symptoms so we will have to see. The Premier League is the toughest place to play so it’s good news but I’m not over-excited because I need to check to see how they are.”
