Celtic are favourites to be the next club Roy Keane takes up a managerial role with.
The Cork native stepped away from his assistant role at Nottingham Forrest on Sunday.
Keane and O'Neill have been a duo for over half a decade after taking the reigns with the Republic of Ireland in 2013, but the former Manchester United star is now looking for pastures new.
The Hoops are 10/3 favourites with Boylesports to be the next club on Keane's CV.
A return to Sunderland, Keane's first venture into management, could be on the cards at 9/2 as well as a potential homecoming to Cork City FC at 5/1.

A host of other English League sides are linked, while the 47-year-old is an unlikely 33/1 to take over at Manchester United - perhaps not helped by his recent criticism of the club's hierarchy on punditry duty.
Sarah Kinsella, spokesperson for BoyleSports said: “There are plenty of managers out there looking for a club to take over and now Roy Keane has been added to that list.
"We make him 10/3 to take over Celtic, 9/2 for Sunderland and 5/1 to return to his native county and manage Cork City. The Derby job may well be available soon too so we’re cautious at 11/2 that he may be lined up to replace Frank Lampard.”
