Interim Chelsea manager Guus Hiddink has said that he is "delighted" with his side's performance in their FA Cup clash with MK Dons this evening.

The Blues cruised into the fifth round of the competition with a 5-1 victory at Stadium:mk as Oscar netted a first-half hat-trick before Eden Hazard rolled home his first of the season from the penalty spot and Bertrand Traore capped off the scoring just past the hour.

Hiddink acknowledged that there was a danger of complacency up against Championship opposition, but praised his side's professionalism in getting the job done.

"We are delighted. Because if you play this game it's always difficult," he told BBC Sport.

"If you play the big games, the big teams, the concentration is always high automatically, but these games you have to be well prepared mentally.

"We played well in the first half but we weren't finishing it off in the first 20 minutes. Then they got the equaliser but we reacted very well."

After the match, Chelsea were drawn at home to Manchester City in the fifth round.
