Chelsea started the game much the better side and finally got the opener just after the half-hour mark.
It came from a United free-kick as the hosts cleared and then countered at pace.
Willian started the move, bursting forward before finding Eden Hazard and the Belgian returned the favour, sending Willian away and clear and he duly powered past David De Gea at the near post to open the scoring.
The Spaniard really ought to have done better, not that Chelsea minded.
