Pep Guardiola bluntly reminded Manchester City's forwards that they need to score goals if they want to play under him.
City have had uncharacteristically struggled this season in front of goal, with the five that they put past Burnley half the number they had managed in their previous eight games combined.
Guardiola has defended his players during their early troubles, insisting that the team were not far away from returning to the prolific form that has seen them top the Premier League scoring charts for the last three consecutive seasons.
If Mahrez's hat-trick suggested that the team could be on their way to doing that, the manager used the goalfest to turn his attention onto Gabriel Jesus, Raheem Sterling and the rest of City's attackers as he made it plain that they must do their jobs.
"The last week and few days have been much, much better. We saw him sharper when he was not before," Guardiola said.
"Of course it can help us, especially for Riyad. For the other ones, Gabriel has to score goals, the others have to score goals, Sterling when he plays has to score goals. They haven't scored much and have to score goals. That is the reason why they are here and play up front."
