Andy King says the FA Cup is hugely important to everyone at Leicester City.
While promotion rivals Cardiff City made 11 changes and paid the price at Macclesfield Town, City took no chances against Burton Albion on Saturday.
Manager Nigel Pearson made just three changes to the side that beat Huddersfield Town in the Championship four days before.
The competition may be seen as a distraction by some promotion-chasing outfits, but King said the FA Cup is still a key part of the season.
"The Cup is massively important," said midfielder King. "You only have to look at last season and the run we went on, and who we played against. That is what everyone wants to do.
"We got to the quarter-finals last year and lost to Chelsea. If you miss one of the big teams then there's a chance you can win again and get into the semi-final at Wembley. Then anything is possible.
"It is also about keeping the winning mentality going. We have won three games on the spin now and that gives us confidence going into the league."
Despite Cardiff's exit, and the suggestion they were happy to be out of the Cup so they could concentrate on the league, King refuses to believe any professional would be happy to lose any game of football.
In fact, King said the Cup win over Burton would add to the rising confidence within the City camp.
"I don't know any players who don't want to win," he said.
"You should go into every game wanting to win. That is the mentality you need around any club.
"That is the mentality we have at this club and, if you aren't bothered if you lose, that sets you back to square one for the league.
"We needed to keep the run going and we have done that with a good performance against Burton."
