Simon Donnelly has backed former Celtic team-mate Tony Mowbray to bring success to Parkhead despite a difficult first season in charge.
Celtic go into Saturday's home game against St Johnstone 13 points behind Scottish Premier League leaders Rangers, who face St Mirren in the Co-operative Insurance Cup final.
Celtic's only hope of silverware appears to be the Scottish Cup, with a semi-final against Hibernian or Ross County.
Mowbray has always promised long-term success to Celtic playing with style, but is under pressure to ensure the club does not end a season without a trophy for the first time since 2003, when they had the consolation of a UEFA Cup final appearance.
However, Donnelly believes Mowbray's honesty and determination will ensure he turns Celtic's fortunes around.
The Partick Thistle midfielder said: “From a fan's point of view, it's a bit disappointing.
“You would prefer to be a bit further up the table and closer to Rangers. It's not looking like that this year.
“They are still in the cup obviously and hopefully Tony can build a squad that's good enough to challenge next year.
“Like any new manager, you need time to get your own players in and get your ideas across.
“Unfortunately at the Old Firm, sometimes you don't get that time, but hopefully Tony will and the boys can do well next season.”
