ANDY Ambler believes the club made a mistake by not immediately replacing first team coach Des Bulpin when he parted ways with the club in September.
Bulpin left the club a month into the season when the Lions were towards the top-end of the Championship table but Ian Holloway did not bring in a successor straight away.
Nigel Gibbs was eventually added to the backroom team in mid-December but Ambler admits it was an error not to strengthen Holloway's coaching staff sooner.
"It was a mistake," Ambler said. "We should have brought in somebody like Nigel straight away.
"Hindsight is a wonderful thing but when Des left we'd picked up ten points out of 15 and the squad was doing well. Progressively things have changed.
"I think the manager has tried to do too much himself during the last few months.
"Sometimes the manager has to step away from things for a couple of days and sometimes having a more experienced coach can be invaluable, so Nigel is really important for the rest of the season.
"I only wish he'd have been in place in September, so getting him in was critical."
