Dario told CreweAlex.net, the official site; "Paul has asked to leave and we have accepted his decision. He first came to us in pre-season asking to go, but we refused at the time because we had spent a lot of time with him trying to develop him as a player.
"There comes a time where you have to stop hitting your head against a wall and we are making Paul available either on a free transfer or on loan. He has a year left on his contract here, so it maybe that he elects to go out on loan for the time being.
"We have circulated his details and are waiting for a response. Because he has not been able to train or play as often as he would've have liked, he has slipped down the order here. He is now sixth choice and I still believe playing up front is James Robinson's best position."
Paul made a total of 13 appearances for Crewe without scoring, whilst going on loan to Stafford Rangers and Southport over the past couple of years.
