The former Wycombe central defender was well down the pecking order at Fratton Park and not in their first team squad when he was picked up by Chris Hughton.
Mike Williamson: “I’m really happy for the Pompey lads because I’ve still got some good friends there.
“For them to have such a good day out, and achieve what they have with all the stuff that’s gone on off the pitch, is a good thing for them.
“Personally, without a doubt, I’ve 100 per cent got no regrets.
“I’m more than happy to be in the position I’m in.
“At Wycombe we got promoted from League Two. I had a little medal from that, but this is by far my best achievement.
“I’m going to get all my shirts signed, and get them up on the wall and milk it for everything it’s worth!
“To be honest, it’s been a walk in the park coming here.
“It’s easier to walk into a winning team, and I’m just really pleased to have fitted in like I have done and played so many games.
“It’s a small, close group of lads.
“The first week I was here, there were a few signings – me, Wayne (Routledge) and Fitz (Hall) – and straight away the senior lads like Kevin Nolan and Alan Smith said ‘right, we’re going for a meal out’, and that set the standard.
“It’s all about the togetherness and bonding, and that’s shown on the field.”
