Liverpool hero John Aldridge believes Jurgen Klopp will still be smarting over the manner of their Champions League collapse at Napoli.

Aldridge wrote for the Sunday World: "This will have been one of the most uncomfortable international breaks Jurgen Klopp has lived through during his time as Liverpool manager.

"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.

"He described the 4-1 defeat against Napoli earlier this month as the worst performance he has witnessed from his team since he took over as Liverpool manager, and that was a pretty big statement.

"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."
