Goals from Stevan Jovetic and substitute Samir Nasri eased Manchester City into the FA Cup quarterfinals with a 2-0 win over Chelsea.
In a match that bore little resemblance to the dominant performance from Jose Mourinho's men in the Premier League encounter less than two weeks ago, Jovetic put City in front after 16 minutes with a cool finish of a slick move by the hosts. That goal came just moments after Jovetic had clipped the bar with a rebound opportunity.
Midway through the second half, Nasri played David Silva through and, while it looked as though Silva had strayed offside, he quickly switched possession back inside to the onrushing Nasri, who tucked the ball into an open goal.
City had the ball in the net again but this time it was ruled out for offside against Joleon Lescott. However, they were rarely under threat at the other end and continued another march towards Wembley -- they already face Sunderland in the League Cup final on March 2, and have reached the FA Cup final in two of the previous three seasons.
Wigan kept their dream of winning a second successive FA Cup alive with a 2-1 win at Cardiff City.
