"We've got a great bunch of players here," he said. "It's always interesting when new players come in and you see how they fit in with the players that are already here.
"But it's like one big happy family here and everyone gets on well with each other.
"We did ourselves justice out there and showed a lot of character to come back."
Folan also believes Hull will reap the benefits of an early return to pre-season training.
"We've kept things as normal as possible during pre-season and everyone seemed very relaxed before the game, and then when the match started we went back to how we were last season," he added.
"I think we've been quite clever with pre-season this year, and I think it definitely showed there today."
