Thomas Tuchel said "super hungry" Chelsea have their sights set on reaching the Champions League final after Hakim Ziyech ended his goal drought to inspire a 2-0 win against Atletico Madrid in the last-16 second leg on Wednesday.

Morocco forward Ziyech grabbed his first goal since October to put the hosts ahead in the first half at Stamford Bridge.

Emerson came off the bench to score the late goal that sealed a comfortable 3-0 aggregate victory over the lackluster La Liga leaders.

Adding to Atletico's misery, Stefan Savic was sent off in the closing stages for elbowing Antonio Rudiger in the stomach.

While Chelsea were the superior side for long periods, Atletico could justifiably claim they should have had penalty for Cesar Azpilicueta's challenge on Yannick Carrasco when the score was still 0-0.

Tuchel admitted it could have been a penalty, saying, "Azpi got a bit frightened because his ball was short, I was a bit frightened as well."

But Atletico boss Diego Simeone added, "We are not looking for excuses. We were beaten by a better team. We tried to press them up the field, but couldn't attack the way we like."

That was the only major scare for Chelsea as they extended their unbeaten run to 13 matches since Tuchel replaced the sacked Frank Lampard in January.

Tuchel boasts the longest ever ­unbeaten start by a Chelsea boss after moving past Luiz Felipe Scolari.

Revitalized by Tuchel, Chelsea have conceded just two goals in his brief reign and are on a run of six consecutive clean sheets in all competitions.

"A very good performance, unbelievable effort. I could feel we totally wanted it," Tuchel said.

"We enjoyed the battle. The guys were totally on and sharp. We were super hungry to go through."

Leading Chelsea into the last eight for the first time since 2014 is another feather in Tuchel's cap as the German eyes a return to the Champions League final following his defeat with Paris Saint-Germain against Bayern Munich last season.

"They play with a special bond. Fixtures and results like this give you a certain edge to achieve special things. I'm pretty sure no one wants to play against us," Tuchel said.

"Quarterfinal means there's only four games [until the final]. It's a big step and feels excellent."

Chelsea, Champions League winners for the only time in 2012, had been eliminated in the first knockout stage in their last four appearances.

But they never looked in danger of losing the 1-0 lead given to them by Olivier Giroud's overhead kick in the first leg in Bucharest.

Azpilicueta escape



Crucially, Azpilicueta escaped without punishment when the defender's under-hit back-pass allowed Carrasco to nip ahead of him in the penalty area.

Azpilicueta responded with a panicked tug that sent Carrasco tumbling but Atletico's penalty ­appeal was controversially rejected by referee Daniele Orsato, with VAR bizarrely opting not to intervene.

Simeone's anger only increased as Chelsea made the most of their good fortune to take the lead in the 34th minute.

Timo Werner now has just two goals in his last 27 appearances for Chelsea.

But Tuchel backed Werner to come good this week and the Germany forward repaid his manager's faith with a strong performance capped by the key contribution to Ziyech's opener.

Breaking at pace after Werner blocked Kieran Trippier's cross, Kai Havertz fed his teammate on the left flank.

Werner accelerated away from the out-of-position Atletico defense before clipping a perfectly weighted pass into Ziyech's path.

Unmarked 10 yards from goal, Ziyech finished Chelsea's thrust with a clinical strike.

Ziyech has fallen short of expectations since his move to Chelsea but Tuchel was impressed by the Moroccan on Wednesday.

"He suffers a bit with our style, he needs to adapt ... but I am super happy, this was reliable from him," Tuchel said.

Savic's frustration boiled over in the 81st minute as he was dismissed for a needless elbow that drew a theatrical fall from Rudiger.

With Chelsea's injured defender Thiago Silva roaring on Emerson from the stands, the left-back blasted home from Christian Pulisic's pass in stoppage time, sparking a wild celebration that encapsulated the feel-good factor fuelling the Blues at present.
