Traore came on in the 57th minute and slotted home five minutes later after being found by Hazard in the box.
His appearance seemed to all be a bit much for him after the game and he caught up on some shut-eye as the Blues made their way back down to London.
And Hazard was on hand to snap a picture of his snoozing team-mate after Chelsea’s impressive FA Cup win.
Hazard posted the photo above on his personal Instagram account and wrote: “Here is what happens when you score your 1st goal for @chelseafc @bertrandtraore10 #mylittlebrotheristired”
Hazard scored his first goal of the season from the penalty spot to add to Oscar’s hat-trick as the west London side sealed a comfortable win at Stadium MK.
Chelsea were handed a home FA Cup fifth-round clash with Manchester City in Sunday’s draw.
