We let fans down - Houston
Peter Houston says his Dundee United side effectively failed to turn up for their Scottish Cup quarter-final replay at Motherwell.
The current holders went down to a 3-0 defeat as the hosts booked a semi-final with St Johnstone after goals from Jamie Murphy, Chris Humphrey and Francis Jeffers at Fir Park.
"We had our second shot on goal in the 89th minute. We were second to every ball and the hungrier side won," Houston told BBC Scotland. "It was a poor performance and we've let a lot of fans down.
"They were hungrier, sharper, quicker to the ball and we stood off people," he continued. "Motherwell got in our faces and, in cup ties, you have to do that. On a surface like this you've got to use the ball and it's not the type of surface to be tippy-tappy.
"They played it like a cup tie and thoroughly deserved to go through: good luck to them."
