Max Verstappen's former race engineer Xevi Pujolar has confirmed his departure from Toro Rosso, as revealed by Motorsport.com earlier.
In the wake of Verstappen's switch to Red Bull, and talk of tension between the Dutchman and team-mate Carlos Sainz, Toro Rosso chiefs have moved to reshuffle its staff too.
It has been decided that Pujolar will be departing the team, which he joined after spells at Jaguar, Hispania and Williams.
The move comes after reports of an argument between Pujolar and Toro Rosso team boss Franz Tost at the Russian Grand Prix.
In a tweet sent on Thursday night, Pujolar said he was now looking forward to his next challenge.
Verstappen acknowledged his former engineer's departure.
