"I am happy with all the players when we speak about defensive work, but we need to improve and take the chances we have," Gracia said.

"We are creating chances but we are not scoring the goals we deserve."

The Watford boss continued: "The best way to have a good chance of getting a good result is try to keep the good things we are doing.

"It's true in the last games we didn't win, but we were closer than the results (suggest). We have confidence we can do it.

"We are able to win if we improve some things."

Leicester secured a place in the quarter-finals of the Carabao Cup on Tuesday night after beating Southampton on penalties.

The Foxes sit just below Watford in the Premier League table following successive draws.

Gracia knows whatever selection Leicester manager Claude Puel decides upon for Saturday's match, his players must be ready for a tough challenge at the King Power Stadium.

"They have good players. You see sometimes they play with (Shinji) Okazaki, sometimes with (Jamie) Vardy, other times with a second striker in (Kelechi) Iheanacho and also (James) Maddison," Gracia said at a press conference reported by the club.

"They have many different options and are well organised. I like the way they are playing this season.

"It will be a very demanding game for us, but we are looking forward to it and we will try to get a good result."

Gracia arrived at Vicarage Road last January to replace Marco Silva, and comfortably secured the Hornets another season in the top flight once again.

The Spaniard intends to be in it for the long haul.

"When you have stability, it is good for the players, the club, and for me as well. It's good news for all of us," he said.

"In this moment, the players can feel well because maybe they prefer this stability, but I said many times I don't need a new contract to do my best or my work 100 per cent."
