Former Wales Under-21 international Lee Fowler wants to leave Blue Square Bet Premier leaders Wrexham and has handed in a transfer request.
The 28-year-old midfielder signed for the Red Dragons, his 12th professional club, in January 2011 before signing a two-year contract extension in May.
But Fowler has struggled to recapture his form since suffering a spell out due to a knee injury in October.
"It's not something I've thought about lightly," said the ex-Coventry player.
"I'm happy off the field. Unfortunately I'm not happy at the football club.
Wrexham player-manager Morrell said a move would be in the best interests of both club and player.
"I think he's a fabulous player," said Morrell. "But, however good you are, if you are not fully right and not focused on the job in hand then maybe it is time to move on.
"It's his decision, he felt he was not playing particularly well and that he is not happy."
Fowler, who turned down offers from Football League clubs to sign a deal with Wrexham, scored twice in 22 games for the Welsh club.
But he has not been a regular during their superb 13-match unbeaten league run, so Fowler has submitted a written transfer request.
"There's no falling out with anyone," added Fowler. "Mozza's disappointed that I'm going and he'd love me to stay. But, unfortunately in football, these things happen."
