PARIS - Atletico Madrid and Real Madrid will fight it out for a place in the Champions League semi-finals next week after the two couldn't be separated in a feisty 0-0 first-leg draw at the Vicente Calderon on Tuesday. The visitors had by far the better of the chances, particularly in the first period, and Atletico were grateful to goalkeeper Jan Oblak for keeping them in the tie with a string of fine saves.

Chile international Arturo Vidal struck a second-half penalty as Juventus laboured to a 1-0 win over a stubborn Monaco in the first leg of their Champions League quarter-final in Turin on Tuesday. Juventus had spurned several chances in the opening half when Monaco, who stunned Arsenal 3-1 at the Emirates on their way to the last eight, also came close, only for Yannick Ferreira-Carrasco to shoot straight at Gianluigi Buffon.

Tempers flared after the break as Madrid defender Dani Carvajal escaped unpunished after punching Mario Mandzukic inside the penalty area. However, for the fourth time this season Real failed to score at the Calderon as Atletico extended their unbeaten run in the Madrid derby this season to seven games.

And the sides meet for the eighth time at the Santiago Bernabeu on April 22. "Obviously you always want to score and win, but it is important not to have not conceded at home," Oblak told Television Espanola. "I don't know (who is the favourite now). Madrid have a great team with a lot of great players so we will see what happens in the return leg."

Real boss Carlo Ancelotti, meanwhile, was left to lament his side not killing the tie off before half-time. "I think that in the first-half we deserved more than to be 0-0 at half-time. We need to highlight the performance in the first-half which was fantastic. In the second-half, Atletico pressured more and the game was more even. It isn't a brilliant result but we have confidence for the return leg, especially based on the first-half performance."

Atletico coach Diego Simeone kept faith with Oblak in goal ahead of the fit again Miguel Angel Moya and that decision paid dividends after just four minutes when Gareth Bale pounced on an uncharacteristic error from Diego Godin, but placed his shot too close to the on-rushing Slovenian, who spread himself well to make the save. "The tie is still open," said Simeone.

The Turin giants, however, were given a break by Czech referee Pavel Kralovec, who pointed to the spot just before the hour when Alvaro Morata, under pressure from Ricardo Carvalho, slumped to the ground on the edge of the area. Monaco's protests that the foul was outside the area went unheard and Vidal, who had blazed over twice in the opening half, calmed nerves by firing past Danijel Subasic and into the top corner. Monaco coach Leonardo Jardim was furious with the result. "We wanted to leave with a totally different result and we will have to play a totally different game if we're to go through to the semis," he said. "But the result was down to a penalty that didn't exist. I'm disappointed. We played a good game, we've got to the quarters and I don't think the score truly reflects what truly happened in the match."

Juventus coach Massimiliano Allegri, meanwhile, claimed the one-goal cushion may not be sufficient to secure passage into the semis.

"It was a good result for us, we didn't concede a goal so we've got a small advantage. But it won't be easy in Monaco." Juventus welcomed back Andrea Pirlo after several weeks of absence due to injury, while Buffon and Carlos Tevez returned to the starting line up after missing the shock 1-0 defeat to Parma at the weekend.
