France international Benzema largely watched on as Liverpool bombarded Madrid's goal in the first half at Stade de France on Sunday (AEST).
Jurgen Klopp's Reds attempted five shots on target in the opening 45 minutes, as many as Liverpool had mustered in their previous two UEFA Champions League finals combined (two in 2018 and three in 2019).
During that first-half rearguard display in Paris, Benzema saw a goal ruled out shortly before the interval after being adjudged to stray offside inside the area.
But Vinicius Junior delivered the decisive strike just before the hour, while Thibaut Courtois thwarted Liverpool as Madrid held on for a record-extending 14th European Cup, more than double any other side.
Benzema became just the second French captain to lift the trophy, after Didier Deschamps with Marseille in 1993, and the Madrid talisman was quick to salute his side.
"We are the best again. It has been a very difficult season for us, and we deserved it again," he said.
"The game was very difficult, but we showed everyone that we are alive, and we won. A final always involves hard work and tiredness.
"We scored an offside goal and got into the game in the second half to end up winning the final."
Benzema also expressed his delight at winning the UEFA Champions League in his home country as he eyes the Ballon d'Or before heading to the FIFA World Cup with France.
"It means a lot to me, it's very important. I'm very proud," he continued.
On the Ballon d'Or, the 34-year-old added: "Let's see if it happens. Hopefully. But the most important thing is to enjoy today's victory."
