Adams: I may've convinced Defoe to quit Portsmouth
Adams said: "Chairman Peter Storrie had a meeting with Jermain last Wednesday, which I sat in on, and Jermain expressed a desire to leave.
"Peter is talking to a few clubs about him. The final decision will be mine and I have a price in mind of what I think he's worth."
He said: "I left Jermain out of those games for tactical reasons and he was very upset. If those decisions influenced his desire to leave, then I am sorry.
"He is a superb player and great goalscorer but I have not made up my mind whether or not I am going to sell him.
