The final whistle goes and that last-minute goal has kept this tie very much alive at 1-1, giving CSKA hope ahead of the second leg in Spain.
GOAL CSKA snatch an equaliser out of the blue in the dying seconds of the game, as Wernbloom volleys home from close range after Real fail to clear a cross into the area.
Ozil is replaced for the final few minutes and it is Raul Albiol who comes on to shore things up in midfield.
Tosic has failed to shine this evening and he is withdrawn now as Slutsky brings on Tomas Necid.
Oliseh exchanges passes with Doumbia down the CSKA right before being brought down by Coentrao, who appeared to get a bit of the ball but has instead been hit with a yellow card after conceding a free-kick.
Callejon goes off to be replaced by Kaka as Mourinho brings on a bit more experience for the final quarter of an hour.
Ramos receives a yellow card for a foul in his own half as Real come under a bit of pressure in the closing stages.
CSKA make another change as the ineffective Evgeni Aldonin is replaced by the much more attack-minded Keisuke Honda, who is only just back after a long injury lay-off.
Ozil is tugged back by Wernbloom in midfield and the CSKA player is rewarded with a yellow card.
CSKA boss Slutsky makes his first change of the evening and it is a surprising one, with the impressive Musa replaced by Sekou Oliseh.
Musa is left clutching his shin after receiving a kick from Xabi Alonso, who becomes the first player into the book tonight.
The whistle goes for half-time and, while CSKA may have started brightly and finished with a minor flourish, it is Real who are well and truly in charge of the tie thanks to Ronaldo's 28th-minute away goal.
GOAL Tosic makes a mess of trying to clear a cross into the CSKA area and Ronaldo takes full advantage to rifle a precise finish past Chepchugov and into the bottom corner.
Gonzalo Higuain is called up from the bench to replace the injured Benzema, and that is a blow for Real after just a quarter of an hour.
Philip John Barber writes: "Let's hope Real start with all guns blazing so that an early goal sparks the blue touch-paper on this fixture! If Alonso has a good game Real should take a lead back to the Bernabeu."
Ryan Williams is the first to get in touch, saying: "I don't think the cold weather will affect Madrid tonight. I can't imagine anything less than 3-0. Ronaldo first goal."
