Jurgen Klopp is proud of his men, as they rescued a draw and held on for the point against Chelsea.
Luiz put Chelsea ahead with a quickly taken freekick in the first half, before Wijnaldum scored the equaliser in the second half.
Liverpool were on the verge of a fourth straight home defeat, only for Mignolet to save Costa’s penalty.
Klopp’s Liverpool are still in the running and just one point behind Tottenham, who are second
“I’m not sure that happy is the right word, but I am proud of the performance because the boys did well against a really strong side,” he told BT Sport.
In a few moments, sure, they were a threat, but they were not as strong as they usually are – that is because of my team, we did really well.
“We gave a very important signal for our fans that we are still there.
“Yes we lost games and yes we didn’t play good football. I think this wonderful powerful club still needs to improve and keep our nerve. Not everything is bad because you lose a football game.
“This team is outstanding in attitude. Let’s do the best we can. We will fight for each point. Everybody saw it.”
