"Last Tuesday's late win against Ajax was a much-needed boost after a horrible start to the season, but you can sense Klopp is concerned by what he is seeing from his team.
"There were worse displays early in his reign, as he bedded down his ideas before he finally got the club winning the biggest trophies in the game.
"Yet, having reached those heights, he would have been shocked to see how far a team loaded with most of the players who took Liverpool to Premier League and Champions League football had fallen that night in Naples.
"Klopp suggested eight out of the 11 players in his line-up that night were well below their best, and he was being generous there.
"We haven't come away from too many matches since Klopp took over with nothing to take away from it, but that's where we were after Napoli."
