Jay Bothroyd believes Cardiff City can win automatic promotion if they put in the same performance that saw them beat Derby County 4-1 on Saturday.
The Bluebirds climbed to third in the Championship on goal difference over arch-rivals Swansea City and are four points off Norwich in second.
"We just have to concentrate on ourselves and we need to win every game," said striker Bothroyd.
"If we can't then we don't want to lose, we want to keep our morale high."
Cardiff top-scorer Bothroyd ended a 10-game goal drought to strike his 18th goal of the season from the penalty spot to set the Bluebirds on their way against Derby.
Dekel Keinan doubled the lead after the break heading home Chris Burke's corner before Paul Quinn made it 3-0 from Peter Whittingham's cross.
And Whittingham wrapped up the points with a volley before Robbie Savage scored a consolation penalty for Derby.
"I think the fact we've won 4-1 at home is big but it's come at a great time as well," added Bothroyd.
"With so little games left, it shows we are in form and we have to go to Doncaster now and back it up with that same kind of performance."
And Bothroyd will be hoping to avoid a third successive heartbreak of missing out on promotion.
"Since I've been at the club there have been disappointments," he added.
"The first year we missed out by a goal, the second year the play-offs and I'd like to get promotion with the club.
"We're third in the league now, we've got some not easy games but almost everyone we have to play are towards the bottom end of the table.
"So we should be putting in performances like that and hopefully getting automatic promotion."
