Manchester City's new striker Sergio Aguero netted twice on a spectacular debut after coming off the bench in its 4-0 home win over promoted Swansea City Monday as the potential Premier League title challenger made an impressive start. The Argentine, who joined in July for a reported City record of $64 million, entered the fray on the hour after Edin Dzeko gave the host the lead and was soon on the scoresheet himself when he tapped in Micah Richards' low cross in the 68th minute. Three minutes later the former Atletico Madrid forward turned provider when he superbly hooked a ball back from the byline for David Silva to slam home. Aguero then fired in a mesmeric fourth goal from distance in stoppage time. “He needs two or three weeks to be 100 percent maybe,” City manager Roberto Mancini told Sky Sports in an ominous warning to City's rivals. “For me he is a fantastic striker, he is young. I'm delighted after this performance but I think in the first half Swansea played very well.” The Welsh side did indeed make a decent fist of the opening exchanges in its first ever Premier League game but the gulf in class soon began to show. City's victory was the only home win of the opening round of English top-flight matches and its fans, bereft of silverware for 35 years before May's FA Cup triumph, will now be dreaming of snatching the league crown off Manchester United next May. The world's richest club took its time to break the deadlock but was solidly on top from the middle of the first half and could have gone ahead when Silva and Gareth Barry rattled the bar while Yaya Toure blasted wide. Bosnian striker Dzeko eased any Eastlands nerves when he tucked the ball away in the 57th minute after Swansea's busy Dutch keeper Michel Vorm, also making his league debut, parried Adam Johnson's shot following a superb driving run by Silva. Aguero, having had no real practice in a City shirt after finishing the Copa America last month, came on just after the goal and almost netted with his first touch as he made one of the most memorable debut cameos English football has seen in recent years. “There is a great bond in this group, I'm feeling the love,” City keeper Joe Hart said.
