Diego Costa's late Strike ,Begin Conte's Era

Diego Costa's late goal gave  Antonio Conte's Chelsea a 2-1 win over
West Ham at Stamford Bridge on Monday.
The Blues were largely dominant and took the lead shortly after half-
time through Eden Hazard's penalty.

The introduction of Dimitri Payet looked to have helped the Hammers,
who lost record signing Andre Ayew to injury in the first half, snatch a
point as his corner was turned in by James Collins in the 77th minute.

Despite the late nature of their triumph, Chelsea - still unbeaten at home to West
Ham in the Premier League since September 2002 – were deserving of the
victory, with Conte celebrating wildly after the controversial Costa struck.
The Blues are back in action away to Watford on Saturday, while Slaven Bilic's
men have a Europa League tie against Astra on Thursday.

Conte threw on Pedro, Michy Batshuayi and Victor Moses in the closing stages
and was ecstatic when his alterations paid dividends.
It was debutant Batshuayi's flick that picked out Costa more than 20 yards from
goal, with the Spain striker finding the bottom corner to seal a memorable
victory, sending Conte wild on the touchline.
