Javi Gracia is looking forward to his first big test as Watford manager.

The Spaniard, who took over from Marco Silva last month, will lead the Hornets against reigning champions Chelsea at Vicarage Road on Monday night. And he's confident his side can upset the Blues.

"It depends on the moment because many times against the same team we play a different way. There is not one way to play against a team," he said.

"I am excited to play at Vicarage Road. I am looking forward to it and I am going to make sure I enjoy it.

"The players are looking forward to the match and want to get the three points for the supporters and see them happy."
