Lewandowski doubles up to give Barça total control

There is another game to be played but on this evidence, Barcelona will do so for just the fun of it, and there may be no one having as much fun as they are right now.

A semi-final place is virtually secure with a second leg to spare after all three of their fantastic forward line scored on route to a 4-0 victory over Borussia Dortmund at Montjuic, the last of them scored by a kid who even at 17 may have a case to be considered the best player on the continent.

Robert Lewandowski, with two, and Raphinha got the others, taking Barcelona to 144 goals this season and almost certainly to the next round and perhaps beyond. They will take some stopping; Dortmund couldn't do it, certainly. Only momentarily did they even get close on a night that began and ended with Barcelona.

The hosts started superbly, Lamine Yamal drawing a save from Gregor Kobel and then bamboozling Ramy Bensebaini, escaping the full-back with a trick before bending his shot past the far post. Raphinha then teed up Lewandowski, whose strike was saved by Kobel. Dortmund were being asphyxiated, shown space beyond Barcelona's advancing back line but denied the time to play a pass into it. Denied the ball too: when they did get it, they had it taken away again, before they could settle.
