Second-half goals from Pedro and Diego Costa earned Premier League leader Chelsea a 2-0 win in a difficult FA Cup fifth-round tie at second-tier Wolverhampton Wanderers Saturday. Pedro headed in after 65 minutes following an intricate build-up involving Costa, Cesc Fabregas and Willian. Costa sealed a place in the quarterfinals in the 89th minute after defender Matt Doherty inadvertently deflected a pass into his path. The prolific Chelsea striker had the time and space to easily stroke the ball into the Wolves goal, finally killing off the Championship side's brave resistance. Having accounted for the Premier League scalps of Stoke City and Liverpool in previous rounds, Wolves looked in the mood to add the division's leaders to that list.

That appeal was turned down by referee Jonathan Moss, but Wolves maintained the pressure.
