Town are in need of a left winger, with no player holding down the position for more than a couple of games.
Quinn and Garvan have both played there, with some degree of success. However Jim was still not completely happy with either.
Charlton are a club at the wrong end of the table, with Addicks boss, Alan Pardrew, coming under heavy scrutiny from the fans.
Pardrew is desperate to reverse this drop down the table and has made the decision to let Ambrose leave to allow for the arrival of one or two new faces at the Valley, possibly Town defensive midfielder Ivan Campo.
