Leicester City boss Marti Cifuentes said his side must "do better" after being booed off in the 2-1 home defeat against Watford.
"It is difficult to swallow," Cifuentes told BBC Radio Leicester. "We started the game well and scored and we tried to push on and get a bigger score but we conceded after a mistake.
"We spoke at half-time that we had to keep our heads up and keep pushing, but we didn't play a good second half.
"Their winning goal was after a sequence of mistakes but we need to be accountable.
