Former West Bromwich Albion midfielder Darren Carter has urged fans to give Alan Irvine a chance.
Irvine was named new Albion manager on Friday.
Carter, who played for Irvine in his first managerial job at Preston, backed the 55-year-old Scot to prove his doubters wrong.
Carter told the Express & Star: "I understand the frustration of the supporters because it's a surprise appointment.
"It was a surprise to me to see Alan and Rob Kelly get the jobs, but I have worked with them so I have first-hand experience and I can't speak highly enough of Alan and Rob.
"Alan is probably the most dedicated coach or manager I have ever worked with. The way he goes about his work, the way he plans his sessions and the way he prepares his teams for games is outstanding.
"He is the most thorough manager I have ever played for and I know that the players at West Brom will enjoy playing for him. He is a manager who will want his team to play football.
"He's not the type of coach who will ask his team to go 'route one'.
"He will want them to play football the right way and he will encourage his players to go out and express themselves."
