Dundee United manager Jackie McNamara reflected on an "excellent" performance following the 4-0 Premiership win at Fir Park.
Ryan Gauld netted twice in the win with Paul Paton and Andrew Robertson also finding the target against the Steelmen.
"I thought we were excellent from start to finish," said McNamara.
"I thought today, we looked a real threat with the chances we were creating."
Gauld's volley and Paton's header put the visitors in command in the first half and Robertson completed the scoring after another fine Gauld effort in the second half.
"They have ability and they have a lot to offer," McNamara said. "Andrew Robertson, I thought was terrific. He got his just rewards at the end with a fantastic finish.
"If anything I was a wee bit disappointed just going in at 2-0 at half-time.
"This is always a hard place to come to. Motherwell had won five out the last six games at home.
"We had to be on our game and today we were."
Motherwell counterpart Stuart McCall described United's display as the best away performance at Fir Park during his time in charge.
"It's very nice of him to say that," added McNamara.
"I've got a lot of respect for Stuart and what he's achieved here, something obviously I would like to try and do up in Dundee with our own team."
Meanwhile, McNamara hopes Gauld will be fit enough to be involved in the Scotland Under-21s match against Georgia on Thursday, despite being taken off just after scoring his second against Motherwell.
