(CNN) -- English FA Cup holders Chelsea secured their place in the last 16 of the competition with a 2-0 fourth-round victory over Preston at Deepdale on Saturday.
Preston, managed by Darren Ferguson - son of Manchester United boss Alex Ferguson - produced a spirited performance but Carlo Ancelotti's Premier League side possessed too much quality for their Championship opponents.
Nicolas Anelka's low strike put Chelsea ahead in the 37th minute before Daniel Sturridge slammed in a second just after the halftime interval to ease any nerves.
Chelsea assistant first-team coach Ray Wilkins, who stepped in for manager Ancelotti at the post-match press conference, singled out Anelka's performance for special praise.
Wilkins said: "From our perspective Nicolas is playing some outstanding football. He is a joy to have around the place.
"He enjoys his training, he is working extremely hard and he is getting the rewards from that."

Jermaine Beckford, who was the hero of Leeds' shock FA Cup victory over Manchester United in the third round, again stole the limelight for Simon Grayson's side as he grabbed both goals for the visitors.
Spurs took the lead through Peter Crouch in the 42nd minute before Beckford levelled for Leeds seven minutes after the halftime break with a well-taken finish.

The Leeds striker dusted himself down and emphatically despatched the resulting spot-kick past Spurs goalkeeper Heurelho Gomes and into the top corner to earn his side a replay.
