Kompany's rocket from 25 yards was the only goal in last season's 1-0 win at the Etihad, a result that proved pivotal as City won their game in hand to go into the final day with an important one-point advantage over Liverpool.
The 4-1 win at Brighton secured the title, but Kompany is credited for his role in City's latest title success.
Kompany said, “I'm not an emotional kind of guy. But it was borderline emotional when I scored a goal, and probably because everyone jumped on me and you couldn't see me. But I thought: 'What if this is the goal, what if this is the clean sheet we keep to the end of the game, and that gives us the title.,' he told Sky Sports.
“The game finished 1-0, the kids came on the pitch, technically my last game for the club at home, and I already knew [I was leaving]. So it was very emotional for that reason. But it's a time I'll never forget, City fans will never forget. Not disclosing it felt right. It wasn't about me, it was about winning what we needed to win, and then after there is always time for goodbyes.
“It was hard to keep the emotion in. I'm looking around and see this iconic stadium for me, and I see 57,000 people I'm genuinely grateful towards, and next to me my 11 team-mates, of which I have a few players in specific like Kun Aguero and David Silva, who I went through everything with, thinking: 'We're still standing and doing this together!' It was a night of emotions.
“That's why I will always remain very humble in my life because I think these kind of things only happen because you stay humble, driven and focused. Eventually, somebody says: 'Here you go, you get your reward.'"
