Fresh from playing a key role in the first goal, Hazard went one better after 24 minutes as he rolled the ball past Foster to double Chelsea's league.
It came from a fine move from the Premier League champions, Cesc Fabregas' ball was clevely flicked into the path of Hazard and the Belgian was clear.
It is not uncommon for players to panic in that position but there was never any doubt as to what the result would be on this occasion.
Hazard kept his cool to round Foster, before rolling the ball into the empty net.
