Failing to win against the likes of Leicester, Stoke and Middlesbrough contributed to City's title charge fizzling out last term and, having once again been installed as pre-season favourites, Kompany believes new-found patience and grit make Pep Guardiola's side a greater threat.
"It's very hard when you see the spending of some clubs in the summer, Manchester United of course and Chelsea who will be right up there. The market is what it is but sooner or later it is going to finish".
We played with the best intentions and it was not enough. We saw this weekend what happened in many games. City had 83 more shots than Chelsea last season but scored five fewer goals; a fit Gabriel Jesus should help transform that.
March, 23, came through the youth system at Brighton, and was named in Chris Hughton's starting XI for the clash against Pep Guardiola's Man City at the Falmer Stadium. "Big congratulations to all the people in Manchester City - we are a strong club".
Before the game Guardiola spoke cryptically about not always playing Aguero and Jesus up front but on Saturday he gave Brighton the full double blast, which paid off - eventually. "We have huge players with lots of talent".
"The season is going to be long, but today was an improvement on what we did last season". We will try to improve.
Brighton's last home game in the top flight was a 1-0 defeat by Manchester City on 7 May 1983. Every game is a battle, especially with the teams who arrive in the first four, five or six games - they are so complicated, especially away.
More immediately, there must be concerns about the way United was outplayed in the Super Cup by Real Madrid, despite in theory being far further along in preparation for the new season.
