A review of Sunday's action in the FA Cup.
The Championship side were no match for the Barclays Premier League champions, who responded to last week's title setback with a dominant display at the Etihad Stadium.
Yaya Toure began the procession early on before Aguero added a penalty and a fine finish either side of a close-range Carlos Tevez effort.
After a quiet opening, Wigan took the lead through the impressive Callum McManaman before Kone increased the advantage five minutes before the break.
James McArthur scored a stunning third for Wigan and, after Lee Novak had pulled a goal back for Huddersfield, Kone seized on a defensive error to score a late fourth.
Juan Mata fired a clinical opening goal after 54 minutes and Oscar, who hit the outside of a post in the first half, tucked in his second goal in four days after 68 minutes.
Mata was the provider for Lampard's 199th Chelsea goal before Terry headed in an 81st-minute fourth as last season's Champions League winners stayed on course for a fifth FA Cup triumph in seven seasons.
