Loovens spent four years at Celtic between 2008 and 2012 and also worked with Carvalhal during his spell at Sheffield Wednesday, so there are few better capable of judging whether the Portuguese coach would be a success in the Scottish Premiership.
The Scottish Sun reported earlier in May that the 53-year-old had contacted Celtic to announce his intention of taking over at the reigning champions.
Carvalhal, who led Sheffield Wednesday to the Championship play-off final in 2016, is keen to get back in the game after failing to keep Swansea City in the Premier League 12 months ago.
And Loovens believes that Celtic could certainly do a lot worse, pointing out that his experience of Turkish football would stand him in good stead in the goldfish bowl that is football in Glasgow.
“I worked with him at Sheffield Wednesday, he’s a great manager and a great person as well,” the current Sunderland defender said.
“I think he’ll do well, he loves the intensity of the game. He coached in Turkey where it can be heated at times and he’d be an excellent manager at a club like Celtic.”
As yet, there is no real suggestion that Celtic would be tempted to give Carvalhal the job with Calciomercato reporting that Claudio Ranieri, Laurent Blanc and even Jose Mourinho are all on their radar.
