Donegal Celtic boss Paddy Kelly weighed in behind counterpart Marty Quinn and his Glenavon assistant manager Pat McAllister, claiming the Lurgan club would be “foolish” to panic.
Quinn was feeling the pressure again after his 10-man side were doubled over by Darren Murray's two strikes after the interval.
Murray cancelled out Conor Hagan’s third minute opener at a wet Celtic Park with a headed goal from Johnny Harkness’ 56th minute free-kick.
He then stabbed the winner home in the 82nd minute as Celtic made the most of substitute Ciaran Doherty’s 62nd minute red card for a hefty tackle on Hoops skipper Stephen McAlorum.
Kelly, who led Celtic to a memorable great escape from relegation last season, said: “I know what Marty Quinn is going through. But there are no better men than him and Pat McAllister to turn things around.
“I have a lot of respect for Glenavon but the club would be foolish to panic at this stage.
“That Glenavon side is much better than the position it’s in. They won’t go down, I have no doubt about that.”
Quinn felt Celtic were handed victory after Doherty’s dismissal.
He said: “I had to take Conor Hagan out of the game because he was on a yellow card and was under pressure — and then Ciaran Doherty gets sent off for what would have been called a fifty-fifty challenge in the old days.
“That led to the game being won by Donegal Celtic.”
