Polish international striker Robert Lewandowski scored all four - the first player to score four goals in a European Cup semi-final - of Dortmund's goals with Cristiano Ronaldo getting Real's.

Dortmund's win sets them up for a probable all German final with Bayern Munich on May 25 after Bayern hammered Real's bitter doemstic rivals Barcelona 4-0 on Tuesday.

It wasn't Real's worst defeat in the competition, that being a 5-0 thrashing by AC Milan in what was then the European Cup in 1988/89.
