Jose Mourinho is convinced goals are on the way for misfiring Chelsea forwards Diego Costa and Eden Hazard.

Costa hit 20 goals in his first season in the Premier League but has just three domestically this term, while Hazard is yet to score in any competition.

But Mourinho was encouraged by the pair's performances against Porto in midweek and is predicting a change of fortune ahead of their trip to Leicester.

"We need results. We need to score more goals," he said. "I know maybe you come back immediately with Diego and Hazard, they are not scoring goals, but the way they played against Porto they have to score goals.

"Sooner or later goals are coming. Their performance against Porto was very good. So in this moment I am less worried than I was."

Last week's home defeat to Bournemouth was an eighth in 15 league games for the defending champions, but Mourinho believes he has solved the defensive problems which saw his side ship three goals to Everton, Southampton and Liverpool earlier in the season.

"We need what we're having now regularly, which is lots of clean sheets, very few goals conceded," he said.

"At the beginning of the season three (goals conceded), three, three, three, two. In this moment, zero (goals conceded), zero, one, zero, one. We are in this defensive stability now."
