Queens Park Rangers star Gareth Ainsworth felt his side's fitness paid off in the second-half of Saturday's win at Coventry City.
The winger said: 'Winning at Coventry is the most important result of the season.
'But it will mean nothing if we cannot get a result at home to Luton on Monday.
The Luton game is a six-pointer. It was always going to be a 1-0 against Coventry.
'We've been doing a lot of fitness work in training, so we are strong in the second half of games and that is especially important over this busy period.'
