Premier League leaders Chelsea have booked their spot in the quarterfinals of the FA Cup, following a 2-0 away win over Wolverhampton Wanderers in an thrilling showdown.
The Blues were under immense pressure, and were lucky on several occasions to survive the first half as Chelsea's defense was repeatedly tested.
The visitors, however, re-grouped after the break to put the Wolves on the back foot, with Pedro heading home the opener in the 65th minute.
The Wolves did fight back but it was marksman Diego Costa who found the back net with a late strike to seal victory as he recorded his 16th goal of the season.
