Dundee United boss Peter Houston says his side still have a lot to do to overhaul Hearts in third spot in the Scottish Premier League.
United's 4-0 win over Motherwell took them to within five points of the Edinburgh side with two games to play.
"It's going to be a mammoth task to try and catch Hearts," Houston told BBC Radio Scotland.
"Now we have to go to Ibrox and try and win. Rangers are buzzing just now, but we've done it before."
United's win at Tannadice followed Hearts' 4-0 defeat by Rangers at Ibrox in the lunchtime kick-off.
Jon Daly was the star man for the Terrors as he claimed a hat-trick, with Andis Shala adding a late fourth.
"Jon Daly is always a threat," said Houston. "He's actually good at providing for David Goodwillie - although he never scored today.
"Today Jon was strong and got confidence from goals.
"But I'm delighted with the whole team. All 11 of them did a good job.
"I think Motherwell have one eye on the Scottish Cup final, if I'm being honest.
"It happened to us last season when you mix up your team a bit."
After facing Rangers on Tuesday, United's final game of the season is against Hearts, who currently occupy the last SPL automatic Europa League berth.
Hearts host Celtic on Wednesday before their trip to Tannadice on Sunday.
"At the end of the day, we've consolidated fourth place and nobody can catch us, so we'll see what happens." said Houston.
