Sergio Aguero was on target as Manchester City denied Brighton any hope of a shock on their Premier League debut.
Pep Guardiola’s side, for all their riches, took time to get into their groove in a 2-0 win at the Amex Stadium.
But the moment they did it was ruthless as striker Aguero converted 20 minutes from time.
Lewis Dunk turned Fernandinho’s cross through goalkeeper Mathew Ryan grasp and into his own net soon afterwards as City prevailed after previously being frustrated.
There was some intricate build-up play and Gabriel Jesus twice found the Brighton net only for the strikes to be ruled out, once for handball and once for offside.
The Brazilian also had a point-blank header saved by Ryan before City’s late burst.
Twenty years after facing extinction and following a 34-year absence from the top flight, Brighton are a Premier League club.
The Seagulls had more recent history with City, knocking them out of the League Cup on penalties at the Withdean Stadium.
Wayne Rooney’s first goal back in blue inspired boyhood club Everton to a narrow opening-weekend victory against Stoke.
After 13 record-breaking years at Manchester United, the 31-year-old made the ideal mark on his Premier League homecoming.
Rooney’s header late in the first half – his first competitive goal for the club in 4,869 days – broke the deadlock and set Ronald Koeman’s Everton on course for a 1-0 win against Stoke at Goodison Park.
