Cristiano Ronaldo has opened the scoring for Real Madrid in their Champions League encounter against CSKA Moscow. You can watch a video of the strike below.

Real led 1-0 at half time in the round-of-16 clash, being played in freezing temperatures at CSKA's Luzhniki stadium.

Ronaldo's goal, a sharp left-footed finish at the back post gives Real a huge advantage going forward in the tie. With an away goal under their belts the already over-whelming favorites to progress become almost certainties to get to the last eight.

CSKA's main hope of progression revolved around getting a good result and preferably keeping a clean sheet at home in freezing temperatures and on artificial turf, which has posed problems for opposing sides in the past.

Real, currenty 10 points clear at the top of La Liga are looking to regain the Champions League, which they last lifted in 2002.

The goal is Ronaldo's 35th for Real in what is turning into another incredible season for the Portuguese forward.

Ronaldo joined Real Madrid from Manchester United for a world record transfer fee in 2009.
