O’Hara was hugely critical of Walsh during his final year in charge of the Yeats County, ridiculing the two-time All-Ireland medal winner in the wake of Sligo’s 2013 Connacht championship defeat to London.
In an interview with Galway Bay FM, O’Hara described Walsh as an “excellent coach” and expects the Galway manager to oversee the county’s promotion from Division 2 this spring.
“Kevin will do very well with Galway, there is no doubt about it. He is the messiah down there and the one thing I always thought about Kevin was that he was a fantastic coach,” said O’Hara.
“He brought fellas along. He made average footballers in Sligo become good footballers.
“But Galway already have good footballers. My own club (Tourlestrane) would have played a good few challenges against Galway clubs last year, the likes of Mountbellew, and some of the club footballers around there are top quality, but none of them really committed to the inter-county scene.
If Kevin can get those guys in, plus the fellas that are already there, I genuinely believe Galway will be a force to be reckoned with in the coming years.
“He will definitely push hard for promotion this year. I have them tipped to get promoted this year.
“It is a big ask and it is a very competitive division, but I do think Galway will be there or thereabouts.”
