Benzema stole the show as LaLiga leaders Madrid moved two points clear of bitter rivals Barcelona atop the table with a 1-0 win over bottom side Espanyol on Sunday.
At the end of a first half in which Madrid had hammered on the door without finding a way past former goalkeeper Diego Lopez, Benzema came up with a moment of sublime skill.
Benzema played a backheel through the legs of defender Bernardo Espinosa to grant Casemiro a simple finish for the decisive goal on the stroke of half-time.
"It was a good play, but the most important thing is the goal afterwards," Benzema said afterwards. "Casemiro gets it right. We are very happy."
Pressed on the piece of skill, the French forward added: "I see football like that! I knew Casemiro was coming from behind."
The goal was as important as it was arresting, as Madrid capitalized on Barca's failure to beat lowly Celta Vigo on Saturday.
"Of course we look at what Barca do, even though we are very focused on us," Benzema said. "I am not going to talk about Barca, but we are fine.
"We go from match to match and each game is a final for the LaLiga title.
"We are happy and we wanted to win. We left very psyched to get three points to take home."
Madrid have won all five of their matches since LaLiga resumed in June following the coronavirus-enforced break.
