Manchester City manager Pep Guardiola was a delighted figure after finally getting the better of Borussia Monchengladbach manager Andre Schubert.
Guardiola, while in charge of Bayern Munich, faced Schubert on a couple of occasions last season but failed to defeat his side.
City's 4-0 Champions League win against Monchengladbach was the first time a Guardiola-led outfit managed to defeat Schubert's Bundesliga team.
After the game, Guardiola said: "I never won before against this coach and he always creates a lot of problems for my team.
"Today we created a really good performance except for 10-15 minutes in the first half."
The win was created by Sergio Aguero's hat-trick and a late goal from City youngster Kelechi Iheanacho.
