Manchester City qualified for this year’s Champions League, thanks to a 4-0 drubbing of Real Madrid on Wednesday night.
The two teams played out a thrilling 1-1 draw in Spain last week.
However, the Premier League champions took complete control of the tie at the Etihad.
Bernardo Silva’s brace put City two goals up, before Manuel Akanji made it 3-0 in the second half.
There was still time for Julian Alvarez to come off the bench and add a fourth.
Pep Guardiola’s men will have the chance to win the trophy for the first time in their history when they face Inter Milan on June 10 in Istanbul.
Inter saw off city rivals AC Milan 3-0 on aggregate in the other semi-final.
