Liverpool winger Luis Diaz has demanded improvement from his team after Wednesday's ruthless 4-1 loss to Napoli.

Diaz says his second-half goal was 'worthless' as the Reds were trampled in Naples.

He told ESPN, via Gol Caracol: "The goal I scored was worthless. It would have been important if it helped the team more.

"We have to improve and look at what is being done for what is coming, which is much more important. We are in this together and I know that this will change.

"After I scored the goal, I felt much better emotionally and it was easier. I had that confidence, that desire to get the team going and try to turn the result around. But it was complicated because they were already many goals ahead."
