Chelsea booked their place in the last eight of the FA Cup as they beat a young Manchester City side 5-1 at Stamford Bridge on Sunday.
The two sides were tied 1-1 after 45 minutes, with 19-year-old David Faupala having cancelled out Diego Costa's opener.
The hosts ran away with the game after the break, however, as Willian, Gary Cahill, Eden Hazard and Bertrand Traore all netted to see out a comfortable victory.
Both clubs revealed their respective lineups before kick-off, with City naming a number of unfamiliar faces:

The weak Sky Blues lineup had been expected after manager Manuel Pellegrini labelled the match "not a real game" due to it's proximity with City's Wednesday clash at Dynamo Kiev in the Champions League, per the Independent's Miguel Delaney.
But BBC Match of the Day pundit Graeme Le Saux accused the Manchester outfit of disrespecting the FA Cup with their team selection:

The Blues had the better of the opening exchanges, with Pedro going close in the 14th minute, hitting the post after a neat exchange with Cesc Fabregas.
The home fans then wailed for a penalty minutes later when Costa was brought down in the box by Martin Demichelis, but referee Andre Marriner was unmoved.
Chelsea continued to knock on the door, and Costa broke the deadlock 10 minutes before half-time with a header from six yards after Hazard found him with a clever ball from the left, per BT Sport Football:

Pellegrini's men wasted no time in getting themselves back on level terms, though. Faupala stabbed home the equaliser from close range in the 37th minute.
Chelsea had been caught napping as they celebrated their deserved opener, and Kelechi Iheanacho provided the killer ball from the byline for Faupala to convert.
Pedro was denied from point-blank range in the 40th minute as City goalkeeper Willy Caballero steered the Spaniard's effort away, and the teams went into the break with nothing to choose between them.
Just three minutes into the second half, though, Willian reestablished Chelsea's one-goal cushion.
Hazard found the Brazilian in the box with a smart through ball, and he wasted no time in sweeping into the corner.
Five minutes later, Cahill made it 3-1 when he latched onto a half-cleared corner and sent a fine finish home from the edge of the box. It was a well-struck strike from the Englishman, but Caballero could arguably have done better:

The same was true of Chelsea's fourth. Hazard's free-kick was well-placed into the bottom left corner of the goal, but Caballero had made a big step to his right that proved to be his downfall.
The Argentinian made amends in the 75th minute when he saved Oscar's casual penalty attempt—won when Demichelis felled Traore in the area.
But he saw the ball hit the back of his net for Chelsea's fifth just ahead of stoppage time as Traore put the icing on the cake with a looping header from Oscar's cross.
Fabregas admitted after the match to being surprised by City's team selection and said that confidence was growing in the Chelsea ranks after their recent good form, per BBC Sport's Gary Rose:
You can see straight away we are playing better and better. The confidence grows when you are winning, and that is football, that is life.
We have big games coming up, and the Champions League is a big challenge. We need to be ready for anything.
I must admit I was surprised by the team selection. For us, it was a negative because we would be humiliated if we lost against them.
Chelsea's record in all competitions this season under manager Guus Hiddink now stands at six wins, six draws and a defeat—to Paris Saint-Germain in the Champions League—and the Blues look good to go all the way in the FA Cup this season.
