NYON: Cristiano Ronaldo scored his 100th goal in European club competition as both Madrid clubs celebrated victories in their Champions League quarter-finals first legs.

Ronaldo scored both goals as holders Real hit back from a goal down to win 2-1 away to Bayern Munich who had Spaniard Javi Martinez sent off midway through the second half; back in Madrid Atletico defeated Leicester City 1-0 on a controversial early penalty by Antoine Griezmann.

Bayern, who had thrashed Arsenal 10-2 on aggregate to reach the last eight, went in front after 26 minutes through a header from Arturo Vidal. However the Chile midfielder wasted a chance to double the advantage in first-half stoppage time when he blasted a penalty over the bar.

Madrid felt justice had been done after the contentious award for handball against Dani Carvajal.

The fullback then provided the cross from which Ronaldo equalised two minutes into the second half. Bayern hit a further setback on the hour after Javi Martinez picked up two quick cautions.

Ronaldo took his tally to 100 European goals when he stabbed the ball past Manuel Neuer in the 77th minute to leave Carlo Ancelotti’s men with an uphill task in next week’s second leg at the Estadio Bernabeu.

Bayern were missing Poland forward Robert Lewandowsi because of a shoulder injury while Real, unbeaten so far in the Champions League this season, were without defenders Raphael Varane and Pepe, who suffered a double rib fracture in Saturday’s 1-1 draw with city rivals Atletico.

Real coach Zinedine Zidane said: “A tie is never decided in the first leg, but we played a good match. We probably could have scored one or two more goals but we’re very happy.

“We showed the willingness to get a good result after the first half and if we had gone in at 2-0, it may have been a different match.

“But we showed patience and managed to get an equaliser, from then on, it was a different game as we showed more personality and won the ball back better.”

Ancelotti said: “We had no luck tonight and it was the small details which made the difference. “We missed the penalty when we could have made it 2-0, then we conceded right at the start of the first half and that changed the match.

“It will be more difficult in Madrid, but we still have a chance, we are still alive. We will look to take our chance. We will try to do our best.”

Leicester lose

Leicester winger Marc Albrighton insists referee Jonas Eriksson was wrong with his crucial penalty decision in their defeat away to Atletico de Madrid.

Eriksson awarded the penalty when Albrighton brought down France forward Griezmann despite the offence taking place outside the box. The 27-year-old conceded it was a foul but was adamant Eriksson made a first-half blunder.

He said: “I asked the ref about the decision after the game and he said the foul was on the line. That’s his verdict on it but TV replays have shown it was outside.

“It was a clumsy challenge but my first thought was to not let him in the box. The final decision lies with the referee and it’s cost us. We can’t afford to dwell on it and we have to put it out of our minds as soon as possible.”

Manager Craig Shakespeare said: “It’s a real disappointment. It’s a key moment in the game. It’s a really disappointing decision by the referee. He has to get that one right. You can’t guess on those ones. It’s a free-kick, it’s a definite free-kick, but it’s outside the box.”

To make matters worse Robert Huth received his third caution of the competition and will miss Tuesday’s second leg. Captain Wes Morgan is also battling a back injury and remains a doubt, with Yohan Benalouane the only recognised centre-back currently available.

Shakespeare said: “I’ve just told Wes in there that when we get back to the hotel, he’s getting his kit on, going to the gym and making sure he does a session.

“We were always on the tightrope with people like Robert because he’s a very competitive centre-half. As you say, it was a very competitive game.”

Leicester did not manage a shot on target but Shakespeare believes they have a chance of reaching the semi-finals.

He added: “I’ve seen enough throughout the squad, through working with them. We know what we’re about at the King Power. We know what we’ve got to do.”
