Chelsea's Oscar performance irresistible for MK Dons

Oscar smashed a scintillating first-half hat-trick to hurtle Chelsea into the fifth round of the Emirates FA Cup after an emphatic 5-1 victory.

The seven-time winners – including in 2009 when Gus Hiddink was also in charge – put their chaotic Premier League in the locker with Brazilian genius Oscar top of the bill and will be at home to Manchester City in the next stage.

CRASH. 15th minutes: a dreadful Kyle McFadzean backpass ended up with Diego Costa sliding the ball across the goal area for Oscar to add the last rites.

BANG. 32 minutes: Oscar met Ruben Loftus-Creek's tantalizing through ball to fire across David Martin and into the net.

WALLOP. 44 minutes: A fabulous solo run and shot clinched his quickfire treble.

An Eden Hazard penalty and a fifth goal from sub Bertrand Traore completed the goalfest.

Chelsea are now unbeaten in nine matches in all competitions. On the evidence of this stroll in the park they are on the way back, having made this tonking look like a battle between Premier League stallions and Championship colts.

The Dons have summoned up the horsepower for a showdown like this, having won four of their previous 11 cup matches against Premier League opposition in beating QPR in the FA Cup and Manchester United, Blackpool and Norwich in the League Cup.

But this was a different story as the Blues ensured there was no repeat of last year's embarrassing 4-2 FA Cup defeat by Bradford.

Darren Potter unleashes MK Dons' deflected equaliser

Any signs of a Cup hangover from that upset were quickly put to one side as Oscar had the visitors in front, sliding home a low cross from Costa that had goal written all over as soon as McFadzean made a howler of a backpass that let in Costa to tee up Oscar for a virtual open goal.

Oscar had seen an earlier shot saved by Martin, who was soon in action again, this time falling on a decent effort from promising youngster Ruben Loftus-Creek.

The battling Dons, being hurried forward by nifty midfielders Rob Hall and Josh Murphy, were far from overawed and soon replied in kind with a spectacular equaliser. Deflected wildly of Nemanja Matic it may have been, but Darren Potter's long range drive was a good 'un and sailed past Thibaut Courtois.

But the Dons' final ball, indeed their overall play in the final third of the field, was not good enough.

Eden Hazard celebrates his first goal of the season

And so Eden Hazard was next up, strolling clear to force the onrushing Martin to instinctively knock his drive on to the post before both Oscar and Cesc Fabregas somehow failed to touch in a 26th-minute Hazard cross with the goal begging.

It was no real surprise then when Oscar struck again, slotting expertly past Martin after taking a beauty of a pass from Loftus-Creek, who accepted another first-team chance with open arms.

Hazard kept up the pressure with another long ranger before Jake Forster-Caskey gave MK Dons fans a welcome shake in firing just over four minutes before the break.

Home supporters – not to mention Dons boss Karl Robinson – needed a fillip and it was beginning to look embarrassing. 

And Oscar brilliantly underlined the fact with a masterclass third goal.

Oscar drills home his third goal

Taking possession 30 yards out on the left, the deft Brazilian cut inside, slid past three desperate Dons defenders and fired past a startled Martin from the edge of the box.

It was sad that a full Stadium:MK should see the home side annihilated like this but Robinson's men are the lowest scorers in the Championship and the Dons' defence looked overawed by the current Premier League champions breaking at them with such pace.

This point was cruelly underlined in the 55th minute when Potter pushed Hazard to the deck as the Chelsea playmaker sped for the byline.

Hazard dusted himself off to take the penalty himself for his first, surprising as it may seem, goal of the season.

Hall tested Courtois five minutes later with a 20-yard flier tipped to safety but seconds later in the 62 minute Hazard chased down a ball to lay it into substitute Bertrand Traore's path for a precision-made fifth Chelsea goal.

Dons' sub Daniel Powell forced Courtois into a late save but by then the game was long gone.

This was only MK Dons' 12th appearance in the FA Cup since their formation and they have never gone beyond the fifth round. 

All they can look back from Chelsea's visit is a cruel lesson in super-fast counter attacking play and clinical finishing.
