Record crowd watches Chelsea Cup clash
Despite a wholehearted performance, the reigning Premier League champions showed their class although the Dons had initially cancelleda out Oscar’s opener through an effort from Darren Potter.
However, Oscar went on to complete his hat-trick while Eden Hazard and Bertrand Traore also got on the scoresheet to secure their passage to round five with a 5-1 victory.
The first real action of the afternoon saw David Martin pull off a magnificent save to deny Diego Costa from point-blank range after he had been teed up by Oscar.
Oscar, himself, then fired two efforts off target as the Premier League champions started on the frontfoot.
The Dons hit back and Samir Carruthers saw a shot blocked after a quickly-taken free-kick, this prior to Martin denying Branislav Ivanovic from close range.
However, there was nothing Martin could do on 15 minutes to stop Oscar, who slotted home from 12 yards after being fed by Costa.
But the men from MK1 were level just six minutes later, a Darren Potter effort deflecting over the reach of Belgium international keeper Thibaut Courtois which sent stadiummk into raptures.
Martin was again at his best on 25 minutes to deny Eden Hazard after the PFA Player of the Year had broken free down the left.
Shortly afterwards, Costa couldn’t get enough on Hazard’s dangerous delivery, but Oscar doubled Chelsea’s lead on 32 minutes when he fired across Martin from 15 yards.
Robinson’s side regrouped and went close through Jake Forester-Caskey, who fired just over the top from 25 yards.
However, Chelsea opened up a two-goal lead on 43 minutes when Oscar completed his hat-trick courtesy of a fine curling finish from the edge of the box.
The Dons started the second half brightly but the referee handed the visitors a penalty for an apparent trip by Potter on Hazard, who picked himself to send Martin the wrong way.
Robinson’s men refused to give up and Rob Hall forced Courtois into a superb save just before the hour mark from 25 yards.
Substitute Betrand Traore made things even more difficult for the Dons on 62 minutes, expertly sweeping home Hazard’s cut-back from the left.
Substitute Daniel Powell almost reduced the arrears with just over five minutes remaining but, after beating three defenders, Courtois denied the winger from finding the net 15 yards out.
Not the result the Dons were hoping for but an occasion to saviour as the Club continues to make history.
