Chelsea co-owner, Todd Boehly, spoke with Pierre-Emerick Aubameyang over the phone to give the player reassurances over his future.
Aubameyang only joined the Blues from Barcelona on transfer deadline day and made his debut against Dinamo Zagreb on Tuesday night.
The Gabon striker returned to the Premier League to be reunited with Tuchel, who he first worked with at Borussia Dortmund.
However, the reunion lasted only 59 on-pitch minutes, with Tuchel sacked on Wednesday morning after the defeat in Croatia.
According to The Telegraph, Boehly made a personal call to Aubameyang in addition to offering wider reassurances to the squad.
Boehly assured the 33-year-old that he was a “club signing”, not just a Tuchel signing, and will still have a role to play under the incoming new manager.
The player is reportedly “appreciative” of the measures taken by the owner.
