As of my last knowledge update in January 2022, I don’t have information on the most recent developments in the situation you described involving Youssef Msakni, Sami Trabelsi, and the Tunisian national football team. If this information is accurate, it indicates that Youssef Msakni may be absent from the Tunisian national team on January 2 due to his commitment with the Qatari club Lakhwiya, potentially playing against PSG.
Sami Trabelsi’s statement suggests that while he may not have an issue with Msakni participating in the match, the final decision rests with the executive of the Tunisian Football Federation (FTF). To get the latest updates on this matter or any changes in the situation, I recommend checking recent sports news from reliable sources, the official statements of the Tunisian Football Federation, or any announcements from the involved parties.
