Mazzarri is under huge pressure to keep his job at Inter and faces Sinisa Mihajlovic's Sampdoria tonight.
Going into the game, Mihajlovic has made it no secret he would welcome talks with Inter about succeeding Mazzarri.
A former Inter player and assistant coach, Mihajlovic is a favourite of the Nerazzurri support.
And with Thohir watching on, Inter fans could jeer and whistle Mazzarri tonight while cheering on Mihajlovic during the 90 minutes.
