Atletico Madrid keeper Jan Oblak made six saves in that half. What a 45 minutes from the 22-year-old former Benfica keeper. He has been a wall out there.
Sergio Ramos takes a whack to the head and that's half-time.
No score in Turin.

Ridiculous pace! Atletico work a short corner which doesn't work out, Raphael Varane cuts it out on the edge of his own box and just sets off, like a young Martin Offiah, bursting down the wing for 60-70 yards!
He pulls it across, Karim Benzema finds James Rodriguez and his low drive is once more saved by Jan Oblak. One-handed. Top save. If Garth Crooks did a Champions League team of the week, your man Jan would be nailed on.
Joshua Edwards: Would hate to be stranded on a desert island with Ronaldo and limited food - Has to be the greediest and most selfish guy ever.

Closer! Real Madrid are not so much knocking on the door as just holding down the doorbell now. Luka Modric the next to go close with a Galactico toe-poke, 25 yards out with the power of a comic book character, inches over the bar. A goal for the visitors before the break?
You've got no right to use your left foot there! Brilliant piece of play from James Rodriguez as the World Cup golden boot winner hits a bending shot with the outside of his left foot, 22 yards out and Jan Oblak makes yet another great save. Real could be home and hosed if it wasn't for the Slovenian keeper.
At the other end Sergio Ramos then gives the ball away and Antoine Griezmann shoots at Iker Casillas.
Rich Howes: Anyone who has any doubts about Bale and free kicks should tune into a Wales game.
Mark Robinson: You've got to ask why doesn't Bale take some of these freekicks as Ronaldo hasn't got the best record at them
Here's one for any Spurs fans out there - who's been the biggest loss, Gareth Bale or Luka Modric?
I ask as the Croatian sensation weaves out of three tight tackles to brilliantly keep the play moving. A little genius of a player. I saw him score a cracker at Bolton once.
Diego Simeone is box office isn't he? On his feet, out to the touchline and pumping up the crowd, demanding even more noise.
Clean as a whistle! Lovely hit from Gareth Bale, spinning away from a tackle to lash one in from 25 yards, dipping and swerving but Jan Oblak again watches it all the way to make a fine stop.
phone systems: Gareth Bale went to Real and all the focus was on hair style, dress sense, cars - football became secondary hence his downfall
Chris Baldwin: I thought the Alice Band was Galactico standard issue? Redondo,Woodgate,Guti,Ramos,Beckham and now Bale
You try taking free-kicks from Cristiano Ronaldo. No chance.
Goalless at the half-hour mark and this game may just be settling down. the visitors should be ahead but now Atletico are just growing itno the game more.
Madan Roka: Why does CR always take the freekicks? There are better freekick takers like Toni Kroos and Modric. Bale used to be good too
Artful Dodger: Ronaldo should allow Bale take any further freekicks
Real Madrid have been hugely impressive tonight. Don't forget, on their last Champions League outing they were given a torrid time by a team full of teenagers for Schalke. Different gear tonight.
Atletico Madrid have had 29% of possession in the opening quarter of this game. They haven't conceded an away goal though, which is a much more important statistic.
Some fashion advice for Gareth Bale
Alan McBride: Anyone noticed Gareth Bale's hairstyle... dorky to say the least
Jon: Wish Bale would cut his hair, looks like he should be in One Direction*. *Other useless boy bands are available
Cristiano Ronaldo hammers the free-kick but only into the wall as the early breakneck tempo shows no sign of slowing down.
I think the Premier League's claim to be 'best league in the world' is particularly mute at the moment. No team can deal with Glenn Murray, who with all due respect would probably not get a game in El Clasico.
Real win a free-kick in a good spot for Mr. Ronaldo again...
Baz Saikia: Not only is the quality of football better in the La Liga than the Premier League. Recently the La Liga has been more entertaining.
David Nicholas: Sergio Ramos is an absolute beast. No defender comes close in the Premier League.
