According to the Football411 website, the 64-year-old on Tuesday night led his side to the Tunisian top-flight crown, adding another trophy to his vast collection, which includes five titles with Orlando Pirates alone, including a treble in his final season with the Buccaneers in 2011.
The Dutchman has now been tipped as one of the favourites to take over from Gavin Hunt, who departed SuperSport for Bidvest Wits this week, and Krol admits he would relish the chance to return to South Africa's elite division.
"I have a contract with Sfaxien but would gladly come back to South Africa if I get a good offer," he told The Sowetan.
"I love South Africa, I also have many wonderful friends there.
"When I joined Sfaxien in October last year, the agreement was that I can leave at any time if I get a good deal elsewhere. It's simple as that.
"I heard SuperSport are searching for a coach following the departure of Gavin, but they have not approached me."
Krol is, however, not putting all his eggs in one basket, and is already planning for the possibility of staying with the newly crowned Tunisian champions next season.
"It's a great feeling (winning the league). It is Sfaxien's first league title in eight years. Everybody is happy and the celebrations are continuing," he added.
"We did well as a team throughout the season and deserved to win. Credit to the players for a job well done.
"We are happy to be going to the African Champions League again."
