Bayern 'wow' Pep

Bayern Munich's stunning four-goal fightback to beat Juventus had the 'wow' factor for Pep Guardiola as the Bavarians reached the Champions League quarter-finals for the fifth season in a row.

Substitutes Thiago Alcantara and Kingsley Coman scored extra-time goals as Bayern roared back to beat Juve 4-2 in their last-16, second-leg tie and seal a 6-4 aggregate victory.

A stunned Bayern found themselves 2-0 down after 28 minutes at the Allianz Arena as Paul Pogba and Juan Cuadrado struck for the Italians before the Bavarian side floored the Italians with four unanswered goals.

But the hosts left it late as Robert Lewandowski netted on 73 minutes before Thomas Mueller's dramatic equaliser in the 91st minute forced extra time.

Just as Juventus had fought back in Turin to draw the first leg 2-2, Bayern came back in Munich. Thiago put Bayern ahead for the first time on 108 minutes before fellow replacement Coman -- on loan from Juventus -- curled in a superb strike on 110 minutes to cap the fairytale finish.

"Four goals against an Italian team. Wow!" beamed Bayern manager Guardiola.

"I don't know how often that has happened in history that a German team has scored four goals against an Italian side. It was a great game for the fans. We played against last season's finalists and to come back from 2-0 down is very hard."

The fightback keeps alive Guardiola's dream of bringing the Champions League trophy to Munich at the third and final attempt before his high-profile move to Manchester City next season.

It was a heartbreaking end for last season's finalists Juventus.

"Of course I am disappointed," said their coach Massimiliano Allegri.

"But I have to pay my team a big compliment: we played one of the favourites for the title and we played better than in the first leg. That's football, we made our first big mistake after 90 minutes. And they scored from one of their first few chances through Lewandowski.

"We could have reacted better, but we didn't have the strength left to score another goal. We were 2-0 up and we could have been 3-0 up, but it's not easy to get a result here."

Juventus captain Gianluigi Buffon said the tie had been decided by fine margins.

"Football results depend on chances," said the 38-year-old.

"They attacked a lot in the second half and took advantage of their chances. It's always a pity to concede a goal in the last minute of a game, but I'm proud of my team. We are going out with our heads held high."

Meanwhile, after Arsena's 3-1 defeat at the hands of Barcelona, which saw them go out on an aggregate score of 5-1, Arsene Wenger hailed Barcelona's front three of Lionel Messi, Luis Suarez and Neymar as capable of turning football into art as all three struck to eliminate his side from the Champions League.

"We have to admire art and they have two or three players that transform normal life into art," said Wenger.

"I have to say we played against a team with the best strikers I've seen. The three are exceptional and from nothing they can create a chance. We didn't take the chances we created and the quality of Barca's creativity in the final third, especially Messi is exceptional. He didn't miss one first touch in 90 minutes

"For me it is suffering, but it is exceptional what he does."

However, Wenger defended his record in Europe as four of the past six years they have bowed out to dominant Barca and Bayern Munich sides.
