Park was on the list with high-profile celebrities like singer Son Tung M-TP, actor Le Duong Bao Lam, comedian Tran Thanh, and rapper Den Vau.
The South Korean coach placed sixth with a buzzmetric social index (BSI) of 29,745.
Son Tung M-TP was first with a BSI of 174,229, followed by Lam with 91,424.
In March coach Park attracted attention from the media when he attended the wedding of football star Nguyen Quang Hai with Chu Thanh Huyen.
Park's message on social media to full-back Doan Van Hau when they met at Hai's wedding also received great response from netizens.
The poor performance of the national team under his successor, Frenchman Philippe Troussier, is also a reason why Park became a trending topic again, with fans constantly mentioning his name, hoping he would make a return to save the team.
Park currently runs an eponymous football academy in Hanoi and also works as an advisor to the newly established Bac Ninh FC in the second division.
Vietnamese football reached historic heights under him between 2017 and 2023, finishing runners-up at the 2018 U23 Asian Cup, winning the 2018 AFF Cup and entering the third qualifying round of the 2022 World Cup.
