If Italian World Cup winner replaces departing Scolari as manager, it will be his second stint at Chinese football champions
Cannavaro's Guangzhou rumour further fuelled by exit from Tianjin
Fabio Cannavaro has resigned as manager of Tianjin Quanjian, the club announced on Monday, just days after steering them to an Asian Champions League berth and with rumours swirling he will return to seven-time Chinese champions Guangzhou Evergrande.
The Italian World Cup winner, who engineered the club's promotion to the Chinese Super League (CSL) last year and a third-place finish in the top tier this year, will be succeeded by former Portuguese international Paulo Sousa, the club said.
A brief statement by Tianjin said Cannavaro's departure came after "friendly discussions" with the club, which praised the manager for his successful time at the helm.
Neither Tianjin nor Cannavaro gave any immediate indication of his plans, but the 44-year-old Italian, World Player of the Year in 2006, has been linked to a possible move back to Guangzhou Evergrande.
Cannavaro was in charge of Evergrande briefly in 2014/15 and the job is open again after Brazilian manager Luiz Felipe Scolari confirmed at the weekend that he was leaving after wrapping up the club's seventh straight CSL title.
"It hurts me to leave Guangzhou, this group, but that's life," Scolari, 68, said.
"We all came out of this happy: me, Guangzhou, the players, and I hope I didn't disappoint you," he added in a video clip uploaded to Chinese social media.
Scolari did not rule out coaching another Chinese club in future.
"I don't know if I will return to China as a manager. I will start thinking about the future from today. I haven't decided anything. But from now, as I finish up everything with Guangzhou, I will start thinking about my future."
Scolari's side were beaten in the season's final game on Saturday by Cannavaro's Tianjin.
Tianjin's 2-1 victory, coupled with a loss by Hebei China Fortune, propelled them into third place in the CSL, meaning they will contest the Champions League play-offs next season.
Evergrande finished the season six points clear of Andre Villas-Boas's second-placed Shanghai SIPG.
Sousa, a defensive midfielder for such European teams as Benfica, Inter Milan and Juventus, has spent more than a decade as a manager, most recently with Serie A side Fiorentina.
Sousa said he was lured to Tianjin by the ambitions of the club and its chairman, cosmetics and healthcare tycoon Shu Yuhui.
"Mr Shu is investing in football and he wants to keep progressing. He showed me his desire, his ambition and is looking for my support," Sousa said.
The club has aimed high with big-name foreign signings such as Brazilian Alexandre Pato, French striker Anthony Modeste and Belgian midfielder Axel Witsel.
Tianjin said it "fully hopes that Mr Paulo Sousa can lead Tianjin FC to new heights in the new season and bring joy to football fans".
Cannavaro is popular among Tianjin fans due to his winning ways but also his penchant for mischievous posts on Chinese social media that made light-hearted fun of players, such as taking pictures of them sleeping on team buses.
"STAY! DONT LEAVE US! If you must leave, we also wish you [well] and please remember Tianjin fans love you," one fan said on Weibo, China's Twitter-like platform.
Another wrote: "Wherever you go, we will continue to bless you. Tianjin Quanjian is established with your wisdom, your perspiration, and your efforts."
