The Eagles ran out 5-0 winners against Ipswich in midweek in Ian Holloway's first game in charge after Freedman left to take over at a Bolton side currently down in 17th.
"It doesn't surprise me what I'm seeing, I'm very, very proud of what I've done," he said.
"I've taken a team that was in the bottom three and going nowhere with no assets and no money and I've left a team at the top with millions of pounds of assets on a budget that was difficult at times.
"No one can ever take that away from me, what I've build there. But I've got no regrets. This opportunity of managing Bolton, this opportunity of the challenge of trying to get them up the league and out of this league drives me on.
"I'm proud of what I've left, but right now my full energy and focus is on getting Bolton into some sort of momentum that can get us a few points and then we'll see what happens from there."
