London, Dhu-AlQa'dah 20, 1438, Aug 12, 2017, SPA -- A clinical Sergio Aguero strike and a Lewis Dunk own goal condemned Brighton to a losing return to the top flight as they went down 2-0 to Manchester City in the Premier League at the Falmer Stadium on Saturday, according to Reuters. City's Gabriel Jesus had two goals ruled out - for handball and offside - and Pep Guardiola's team struggled to break a stubborn Brighton side down until Aguero fired home a pass from David Silva to open the scoring in the 70th minute. Five minutes later, Brighton defender Dunk slammed a header into his own net as he tried to clear a cross under pressure from Jesus, with the home side lacking the firepower to mount a comeback in the closing stages. In the end it turned into a routine win for Spaniard Guardiola, who gave debuts to four of his new signings. England full back Kyle Walker, who arrived from Tottenham Hotspur for a reported 50 million pounds ($65.06 million), was a constant menace on the right flank and was man of the match. City's breakthrough came within minutes of Guardiola bringing on Leroy Sane, just one member of a star-studded bench from which Bernardo Silva and Raheem Sterling later emerged. For Brighton, it was a disappointing top-tier return after 34 years, ironically against the same opponents who they faced in their final game before relegation in 1983. Despite a wall of noise from the home fans, the Seagulls spent most of the game on the back foot, content to concede possession and setting up a compact defensive unit deep in their own half. In the end they were undone by their own mistakes, with Dale Stephens caught in possession in the lead-up to Aguero's goal and Dunk's own goal sealing their fate in a game City should have won more comfortably given their 75 percent possession. -- SPA 22:22 LOCAL TIME 19:22 GMT www.spa.gov.sa/w464857
