Antonio Conte registered a win in a opening game over Westham

Diego Costa’s late strike gave Antonio Conte an exciting winning begin as Chelsea manager as his side secured a season-opening triumph over West Ham.

The Spain striker found the net from 20 yards in the 89th minute of the game to start wild scenes at Stamford Bridge, with Conte celebrating among supporters.

Eden Hazard had put Blues in front from the spot after Michail Antonio fouled Cesar Azpilicueta.

James Collins leveled for the Hammers, however Costa’s goal settled it.

Chelsea will play against Watford on Saturday after the Hornets began the season with a draw at Southampton. West Ham have a trip to Romania on Thursday for the first leg of their Europa League qualifier against Astra Giurgiu.
