Despite the result, the former Wales and Manchester City boss said: “I loved every minute of it. It’s been a long time since I was in charge of a group of players at a match on Saturday.”
Hughes was given a standing ovation on his way to the dugout, but Mansfield spoiled the party, scoring either side of half-time to condemn the Bantams to their fourth successive defeat.
Leading scorer Rhys Oates put them ahead a minute before the interval with an angled drive after a long clearance had been headed into his path.
Matty Longstaff, on loan from Newcastle, added a second three minutes after half-time with a shot that took a deflection past keeper Alex Bass after the Bradford defence failed to clear Stephen Quinn’s cross.
Hughes said: “It was a great atmosphere. Mansfield came in numbers and the noise our fans made was great. They are disappointed obviously as we all are, but I think they understand it is a process we are going through and we will get better.
“I saw things I was encouraged by, other things less so, but it’s about making sure we emphasise the elements of our play we need to improve and we will get better.
“It was a good exercise in terms of having a better understanding of the group. There were elements of our play I was reasonably pleased with.”
