Latest: MK Dons 1 Chelsea 5 – Blues storming towards fifth round

Eden Hazard scored his first goal of the season as Chelsea built on Oscar’s first-half hat-trick to cruise towards the fifth-round of the FA Cup.

The Belgian won a penalty 10 minutes after the break and coolly slid home the spot-kick for his first goal in his 29th appearance of the season before celebrating in front of the near 7000 travelling fans.

And Hazard then set up substitute Bertrand Traore to make it 5-1.

Chelsea were already in control at half-time after a thrilling, and astonishingly open, first half.

Diego Costa made the most of a terrible Kyle McFadzean backpass to lay on a simple opener for Oscar.

And although MK Dons levelled against the run of play through Darren Potter’s deflected long-range strike, Oscar’s tidy finish and sumptuous curler put Chelsea in control.

Eden Hazard, on his first start since limping off early in the 3-0 win over Crystal Palace, was the key man in a dominant Chelsea display.

He helped create three early chances, once for Costa via Oscar that produced a good save from keeper David Martin, and then twice teeing up Oscar, who miscued from 12 yards on both occasions.

Rob Hall and Jake Forster-Caskey’s pace posed a few problems for the away side, but Chelsea controlled possession and created opportunities at will.

Branislav Ivanovic had a shot blocked and Costa then made it 1-0, but the Championship strugglers levelled when Potter’s 20-yard strike from the edge of the box took a huge deflection off Matic and looped over Thibaut Courtois.

Hazard also squandered a glorious one-on-one opportunity, but a clever Ruben Loftus-Cheek pass put Oscar clear inside the box and he finished tidily across Martin to make it 2-1.

And the Brazilian completed his treble with his best effort just before the break, running across the box and curling home a stunning strike.

Hazard’s strike, after a foul by Potter, and Traore’s first Blues goal made the tie safe after the interval and the score 5-1 with 20 minutes remaining.
