"When I go out on the field I don't just want to score goals", he said after the match.
Julen Lopetegui and Santiago Solari have both gone with Keylor Navas for the Copa del Rey and the UEFA Champions League whereas Thibaut Courtois has been preferred to the Costa Rican in the league matches.
"We have seen handsome goals".
"We came into the game fully focused and it showed", Solari said.
With two games remaining in Group G reigning champions Real are joint top on nine points with AS Roma who beat CSKA Moscow 2-1. CSKA are third with four points, while Plzen sit at the bottom and are out of contention to progress.
Casemiro doubled the lead three minutes later when the Brazilian outjumped his marker and headed home from a corner.
Madrid were dominate throughout and Toni Kroos added an impressive fifth after the interval when he chipped goalkeeper from inside the area.
"It was an important night for us", Casemiro said.
Benzema doubled his tally and set up Gareth Bale in the space of 144 seconds towards the end of the first half, and Toni Kroos floated a lovely 67th-minute chip home to wrap up the win and leave Plzen playing exclusively for third place.
"He is a great coach, we now have more confidence and we are going to compete". Though landing major titles might be beyond the squad this season, they surely should be able to finish in the top four and make the knockout stages of the Champions League, creating a platform for the inevitable rebuilding that will take place in the summer.
Solari spoke to the media after Real Madrid's win over Viktoria Plzen on Wednesday night.
Dani Carvajal has described sacked Real Madrid manager Julen Lopetegui as the best coach he has had in his career.
The hosts were more lively after the break and managed a few shots on goal but could not find the quality they needed in the final third to chip away at Real's lead. Once they play with this seriousness, commitment and wanting to score.
