Hartlepool United have ended Mikael Mandron’s loan move at the club, with the striker returning to Sunderland.
Mandron signed for Pools in November but scored just one goal in seven appearances for the club.
Pools manager, Ronnie Moore said: "It works for some, not for others.
"Mandron came in and never really hit it off, it never really worked for him.
"He's gone back to Sunderland now.
"He's got a groin strain and he’s got two weeks left on the deal more or less, so he's back and we thank Sunderland for allowing him to come here.
"Sometimes it works, sometimes it doesn't."
Mandron scored his first Pools goal against Salford City in the FA Cup second leg at Victoria Park having scored five goals for Sunderland’s under-21 side this season.
After the Salford win, Moore said Pools fans had to show patience with the striker.
He said: "He's a young kid and he’s still learning," said Moore.
"The supporters have to appreciate that.
"People shout and scream this that and the other, but they have to understand the kid has hardly played league football."
