Bolton midfielder Sean Davis joined Bolton because he felt he was not appreciated by the Portsmouth hierarchy.
The midfielder joined Wanderers on a free transfer on Wednesday, six months after Pompey rejected a Â£3.5million bid for the midfielder from the same club.
He told Sky Sports News: "The deal could have been sorted in January. (Then manager) Tony Adams offered me a deal but they kept mucking me about on little things and we couldn't agree on anything."
Davis blamed uncertainty at Fratton Park for his decision to switch Barclays Premier League clubs.
He added: "The contract ran out and I didn't hear anything, so I thought I'd go somewhere I'd be appreciated.
"When I say appreciated I don't mean anything against the (Portsmouth) fans, they were great to me, always behind me, the atmosphere was great and they were one of the special things there.
"But upstairs I didn't feel appreciated enough. The contract could have been sorted months ago."
However, Davis - a former England Under-21 international, added: "There is no bitterness - I'm a Bolton player now.
"After I spoke to the manager there was only one decision - to join Bolton Wanderers.
"I don't want to dwell on it too much. You've got to move on and I'm looking forward to a fresh start."
