Liverpool have lost two straight games in the Premier League and Champions League, but is this a wobble or something more serious?
"Arne Slot's side look so vulnerable defensively," said BBC Sport football expert Chris Sutton. "I covered their defeat at Crystal Palace last weekend and Palace could have gone 4-0 up, no word of a lie.
"Alisson went off injured against Galatasaray, and if he is missing it is not going to help. We know Liverpool can hurt Chelsea but it is the other end they have to worry about."
Sutton is making predictions for all 380 Premier League games this season, against AI, BBC Sport readers and a variety of guests.
