Robert Lewandowski hit a brace to help Barcelona dismantle Borussia Dortmund by 4 goals to nil in a one-sided Champions League quarter-final first leg on Wednesday.
The five-time winners took the lead against last year’s runners-up through red-hot winger Raphinha before Lewandowski reached 40 goals for the season with his double.
Teenager Lamine Yamal was an unstoppable force throughout and deftly prodded home Barcelona’s fourth as Dortmund collapsed.
Barca, which last lifted the trophy in 2015, will visit Germany next Tuesday and aim to seal a final-four clash against Inter Milan or Bayern Munich.
“I think we played very well but we have one more game to go… we always want to play our football and we want to play it there and we will win,” Lewandowski told Movistar.
“If you have 4-0 in the first half (of the tie), in the second half in Dortmund you have to play the same or better.
“In the end it’s the Champions League, and we always want to play at our level.”
Flick selected his typical side, with only one decision to make — he opted for Fermin Lopez over Gavi in attacking midfield to support the dynamic forward trio.
La Liga leaders Barcelona seized control from the start, with Gregor Kobel saving well from Yamal and Lewandowski.
Spain starlet Yamal, 17, fired across the face of goal and then over as he ran riot, Dortmund unable to slow him down.
Barcelona took the lead after Karim Adeyemi needlessly gave away a free-kick in a dangerous area, pulling Jules Kounde back by his dreadlocks while trying to burst forward on the counter.
Lopez whipped it to the back post, with Inigo Martinez nodding the ball towards Pau Cubarsi, who turned it towards goal.
The young defender’s effort beat Kobel and was heading over the line before the tournament’s top scorer Raphinha slid in to make sure, claiming his 12th goal.
The Brazilian winger faced a nervous wait while VAR worked to confirm his 25th-minute strike was onside.
Yamal and Raphinha zipped forward in search of a second but could not get the final ball right, before Serhou Guirassy spurned a huge chance for the visitors to level.
With Dortmund’s first slick attacking move of the game, the forward, who has 10 goals in the competition, was played in but snatched badly at a bouncing ball with just Wojciech Szczesny to beat.
