Everton midfielder Steven Naismith insists there has been no talk of player burnout as David Moyes' squad look to secure a positive end to the season.
Moyes' men have not won in the Barclays Premier League in three attempts, which has seen them fall six points behind Tottenham, who have played a match less, in the race to finish in the top four.
But Naismith insists the first-team group - one of the smallest in the Premier League - just have to roll their sleeves up and get on with it, and he said: "The squad haven't moaned about tiredness, it is not something we've spoken about."
He added: "We're professionals and you have to go out and do your job. We work every day and we work at a good level so the boys are definitely fit enough. I don't think they're tired at all.
"We've maybe not been playing as well as we did at the start of the season but we've ground out some results."
Nikica Jelavic again failed to find the net against Norwich on Saturday, his best opportunity coming early on when a close-range shot was saved by Norwich keeper Mark Bunn.
Everton manager Moyes, though, continues to have faith in the Croatian, who last scored against Cheltenham in the FA Cup on January 7.
"We give him an opportunity to play and score," Moyes said.
"He took one great on his chest in the first half and he was a bit unlucky not to score.
"You can only keep putting him out there. If he scores and gets the goals, he probably wins Everton games. He's really important to us and we hope that he's going to come up with the goods between now and the end of the season."
