Manchester City enjoyed a comfortable 2-0 win at Brighton to open their Premier League campaign.
After seeing Gabriel Jesus' scrambled effort ruled out for a handball and another in the second-half for offside, Brighton looked to be holding out against big-spending City until Sergio Aguero made the breakthrough with 20 minutes left.
The Argentina forward latched onto a pass from David Silva and drilled the ball past Seagulls keeper Mathew Ryan.
Any hopes of a spirited comeback at the Amex Stadium ended five minutes later when Brighton defender Lewis Dunk headed a cross from Fernandinho into his own net.
City boss Pep Guardiola said: "We saw all the games in the Premier League today and yesterday, how complicated it was for everybody. We knew that Brighton are a newly-promoted side, with enthusiasm, also with their crowd.
"But we had chances in the first minutes and after the game was quieter, it's not easy to attack 10 guys in the box.
"We controlled the counter-attacks, we conceded just one chance in 90 minutes away from home and that's not easy in the Premier League.
"We are so satisfied for the first game, the way we played. It was quite similar level to pre-season in terms of working without the ball, and we are going to improve."
