Imperious Barcelona thumped visitors Borussia Dortmund 4-0 in their Champions League quarter-final first leg on Wednesday after Robert Lewandowski netted twice against his old club to earn the Catalans a sizeable lead.

The treble-chasing Barca predictably dominated the opening stages and grabbed the lead following Raphinha’s strike in the 25th minute. A string of saves from Dortmund keeper Gregor Kobel frustrated Barca for the remainder of the first half.
