Motherwell manager Stuart McCall was left ruing his side's failure to go five points clear in second place in the Scottish Premier League.
Johnny Russell's goal gave Dundee United a 1-0 win at Fir Park.
"We're frustrated in the fact that we know what could've happened, the gap we could've put between us and the rest of the pack," McCall told BBC Scotland.
"But there's no disgrace in losing to Dundee Utd and we'll be fully focused going up to Dingwall on Saturday."
Pre-match, all the talk was about Motherwell's re-signing of James McFadden.
And while he came on as a second half substitute, there was to be no dream debut.
Russell's 18th goal of the season came in the 17th minute after Gary Mackay-Steven's impressive assist.
McCall said: "We're disappointed with the goal we gave away. We've got a corner and they break away and score.
"As good as we were on Saturday going forward, I don't think the forward men were at the top of their game today."
On the introduction of McFadden, McCall added: "It's too early to say after 20 minutes. He needs football.
"The more we get him involved I'm sure the better he will be."
