A Sergio Aguero brace was the highlight of Manchester City’s comfortable 4-0 FA Cup fifth round victory over Leeds United at the Etihad Stadium, a win that will lift, at least temporarily, speculation about the future of manager Roberto Mancini.

With City 12 points behind League leaders Manchester United, the FA Cup remains Mancini’s most realistic hope of winning silverware this season and Aguero’s efforts, together with goals from Yaya Toure and Carlos Tevez, carried his team through to the last eight with the minimum of fuss.
