According to RMC (h/t MailOnline's Daniel Matthews), Tuchel is not getting along with sporting director Antero Henrique. Wenger's job would be to work as a bridge between the German and the board.
Wenger has been out of football since he left Arsenal at the end of last season, but reports of a return are increasing. Earlier in October, Bild linked him to Bayern Munich (h/t Get French Football News):
The 68-year-old spent almost 22 years with the Gunners and guided the team to three Premier League titles, including an unbeaten league campaign in 2003-04.
He was replaced by former PSG boss Unai Emery, who made way for Tuchel at the end of the 2017-18 season.
Tuchel has enjoyed a fine start in Paris, guiding the club to nine straight wins in Ligue 1. Per Squawka Football, none of his predecessors managed that feat:
In the UEFA Champions League, Les Parisiens bounced back from their defeat against Liverpool with a 6-1 demolition of Red Star Belgrade.
The former Borussia Dortmund boss hasn't been afraid to take risks, such as moving star forward Neymar into a new central role. The decision has drawn praise:
Tuchel's position seems safe and likely will continue to be unless the club falters in Europe yet again. In Ligue 1, their advantage is already so large the German can afford to rest some of his starters and take even more chances.
Wenger's many achievements command respect, and he's already close to the club because of his ties with CEO Nasser Al-Khelaifi. As the Mirror's Neil McLeman reported, that relationship led to his role as a pundit for beIN Sports in 2016.
