Cardiff manager Ole Gunnar Solskjaer faces a 'culture shock' in the Premier League, according to Malky Mackay.
Scot Mackay was sacked late last year after Cardiff owner Vincent Tan wrote to him requesting he resign or face the axe.
Solskjaer has taken over after his spell with Norwegian club Molde but Mackay believes the former Manchester United striker will need time to adapt to managing in the Premier League.
"It's a great job for him to get, coming from Norwegian football into the Premier League and into a club with that kind of structure," Mackay said on BBC's 'Match of the Day'.
"There are 30,000 people going to their games every week willing them on.
"He has done really well in Norway but the Premier League will be massively different and a bit of a culture shock to begin with."
Mackay spoke glowingly of his time at Cardiff, who he led to promotion from the Championship last season.
The 41-year-old believes his former side can avoid relegation despite sitting in the drop zone after 21 games, only behind West Ham on goal difference.
"I loved my time at the club and being around the place. I loved my time living in Wales," Mackay said.
"I look back on it really fondly. We got to the play-off final and we achieved promotion.
"I think there's a squad there that's absolutely competitive and can stay up.
"They're a great group of players with terrific fans behind them."
Mackay wants to return to management after sorting out issues with Cardiff but said he was yet to speak to anyone regarding a role.
"I've not spoken to anyone at the moment, I'm just taking some time out for now but I would love to get back into management at some point," Mackay said.
