Kilmarnock manager Neil McCann reflected on Martin O'Neill's ability to get his teams over the line as he prepares to renew rivalries with the Celtic boss.
McCann was a Rangers player during the first three years of O'Neill's initial spell in charge at Celtic Park, and will come up against the Northern Irishman again when the Premiership champions visit Rugby Park on Sunday, this time in the opposition dugout.
O'Neill's arrival in 2000 was the catalyst for Celtic becoming Scotland's dominant team, although McCann helped Rangers win the treble in 2003, when the Hoops reached the Uefa Cup final.
The 73-year-old appears to have retained his ability to instil a winning mentality in his team either side of Wilfried Nancy's brief and chaotic reign.
Celtic have only lost once in 17 games under O'Neill this season and have won 14 of those matches. They were down to 10 men in their two draws.
Stoppage-time goals have helped them get over the line in their past two matches against Dundee and Livingston, and McCann recognises the traits of O'Neill's leadership.
"Martin's shown again, and then again, how good a manager he is," McCann said.
"I've played against him when he was a manager at Celtic when I was playing at Rangers, understood what he demanded from his teams, how his teams went about things.
"I think he's just got that something that gets the team going.
"Whether they're playing sparkling Celtic football, as everybody tends to put the label on them, or not, they're finding a way of winning games, so we have to completely respect the challenge."
