Chelsea lost 2-1 at home on Friday night.
"In the second half we started with the same players and you saw another game, with great intensity. We scored the goal and created chances so for this reason I waited to make the substitutions. In the last 10 minutes I changed three players to try to give freshness and change the result," said Conte.
"In that moment I had to decide whether or not to put two wingers in. I wanted to change a midfielder to put Fabregas on but it could have been Batshuayi and not either Moses or Pedro. I needed to put Hazard closer to Diego."
