Former striker John Hartson believes Steve Clarke should be a top contender to take over at Celtic - but may now prefer international management.
The Scotland boss has been among the frontrunners with oddsmakers since Neil Lennon's departure from Parkhead.
However, having led the country to Euro 2020, Hartson reckons it could be hard to tempt the former Kilmarnock boss away from his post.
The Welshman says the international schedule suits come managers, using his old pal Chris Coleman as an example, rather than club management.
Hartson told Football Pass UK: "I really like Steve Clarke.
"He did a brilliant job with Kilmarnock. He's got vast experience and worked under Mourinho for many years and worked at Liverpool as well.
"Steve comes into the fray very high up the ladder for me, but he is the national coach of his country and they are in the Euros.
"It entirely comes down to him about how he feels about club management and international management.
"They are two different things altogether.
"I remember speaking to people like Chris Coleman, John Toshack and Mark Hughes, managers of mine over the years.
"You get the players seven or eight times a year, and if you're someone like Chris Coleman who likes a bit of golf as well, the international set-up will suit you.
"It will suit some managers because they haven't got the day to day activity. So maybe Steve is enjoying that aspect.
"You don't get much bigger jobs than managing your country. It's the pinnacle. It's the top of the tree."
