"I thought we were excellent from start to finish," the Rovers boss said after the 2-1 win against his former club.
"We came here with a positive attitude and possibly surprised a few people with our line-up.
"I thought there were opportunities to cause United problems. We were excellent in the first half and possibly should have gone in at half-time with more than one goal.
"I expected United to rally in the second half and we had to stem that. I was disappointed with their equaliser, but we showed grit and determination to go back in front. I was delighted with the manner in which we applied ourselves to get the result.
"There's been a lot of debate about our style. We've been getting a hard press, but on days like today it's wonderful to be part of Premiership football.
"A lot of people have been quick to criticise the way we do our business, but hopefully they'll give us credit after the job we've done today."
