Paul Robinson has urged caution over the potential appointment of Eddie Howe as Celtic manager.
The former Spurs stopper, speaking exclusively to Football Insider, also urged Celtic to announce their new boss as soon as possible.
Last week, talkSPORT claimed Howe has agreed to replace Neil Lennon at Celtic this summer.
In April, Football Insider revealed Howe had verbally agreed to take over at Parkhead before having second thoughts.
Celtic have tabled what is said by Football Insider sources to be a “wonderful offer” to the 43-year-old.
Robinson claims Celtic fans won’t be inspired by Howe as he has no track record of winning trophies.
“It’s been dragging on for a long time now,” Robinson told Football Insider correspondent Dylan Childs.
“If they are going to announce him as the new Celtic manager they need to get it done. They need to start building for next year and it’s a huge move if he gets it.
“They have fallen so far behind Rangers this season. They are losing Scott Brown as well so there’s a big job up there for Howe.
“Whether he’s the right man or not, time will tell. From a fan’s point of view, I wouldn’t be inspired by Howe.
“He’s got no experience of winning trophies. He’s going from a team like Bournemouth who he had a good time with but he’s never stepped out of his comfort zone.
“The one time he did it with Burnley wasn’t successful. There is an instant expectation at Celtic and it will be a huge test for him.”
Howe managed Burnley between January 2011 and October 2012.
He then returned to the Vitality Stadium before leading Bournemouth to the Premier League.
