The 42-year-old Argentinian dismissed questions about his possible future as Real's head coach. "Football is about the present and it's the next game that matters", he said, with a trip to Celta Vigo on Sunday next up for Real. All matches are different, you have to continue working with humility, sacrifice and ambition for your objectives and think about the next game.
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 attractive 67th-minute chip home to wrap up the win and leave Plzen playing exclusively for third place.
Kroos rounded off the scoring in the 68th minute, curling a sumptuous lob over the stranded Hruska following a pass from rising star Vinicius Junior, who came on as a second-half substitute.
DF Javi Sanchez, 6 - The Castilla centre-back, 21, got his first taste of Champions League action when Ramos was removed on the hour mark, presumably to avoid risk of injury or suspension. CSKA have four points with Plzen on one.
Real overcame an early scare when Nacho cleared a low cross against his own crossbar, while Plzen midfielder Roman Prochazka curled a shot just past Thibaut Courtois's goal.
DF Sergio Ramos, 5 - Very fortunate not to be sent off at 0-0 after he drew blood from the nose of Plzen's Milan Havel with his elbow, which is not the type of leadership Madrid need at the moment.
MF Dani Ceballos, 6 - Given a chance in an advanced midfield role with Luka Modric rested, Ceballos did not have as big an influence on proceedings as he would have liked, although he did hit the cross leading to Benzema's second goal.
In their next Champions League game, Real face Roma in Rome on Nov 27.
