Hazard and Oscar was threat to Arsenal

Chelsea extended their advantage to five points at the top of the Premier League after Eden Hazard and Diego Costa scored either side of half-time to earn a 2-0 win over Arsenal at Stamford Bridge. Tempers were running high even before kick-off, with the match delayed by 20 minutes after reports of away fans setting off flares inside the stadium. The bad blood continued once the action was underway, as Mourinho clashed with Wenger on the touchline after Gary Cahill had clattered Alexis Sanchez - with the Chelsea defender lucky to stay on the field.
