Slot's Liverpool meet Aston Villa today having lost six of their past seven games. But after last season's Premier League title triumph, Crouch believes Slot is secure in his job.
He told Paddy Power: “He's earned enough grace from last season to certainly see this season through. Now there are concerns and there are question marks over the selection and tactics for the first time in Slot's Liverpool career.
“It was one of those where he actually really needed a win in the Carabao Cup, so to change as many players as he did seemed a little bit strange when they're struggling as much as they are. It needed a little bit more quality than what was picked.
“It was such a young side, I know they had injury problems but I think the balance of play certainly needs to be addressed, because it feels like there's a lack of confidence in their defending at the moment.”
