Just months after winning the League One title, Wigan have sacked manager Gary Caldwell.
Caldwell has not been able to replicate his League One success in the Championship, winning only 2 of 14 games.
The decision was announced by chairman David Sharpe, who said the club were now looking for a manager who would have an instant impact.
Sharpe said on the club’s website: “It’s undoubtedly the toughest decision I’ve had to make since becoming chairman.
“We deservedly won the League One title last season. However, we have not managed to carry on that momentum into this season and, after careful consideration over a period of time, I feel that we need to act now in the best long term interests of the club.
“We thank Gary for all the hard work he has put in and wish him all the best for the future.
“We need to identify a new manager who can have an immediate impact and deliver success in the long term.”
Caldwell also won as a player with Wigan, lifting the FA Cup trophy in 2013.
