The young defender signed for the Blues in January and is apparently learning English from the former Aston Villa man.
The Swiss Under-21 international joined the Blues in the January transfer window, signing a four-and-a-half year deal until 2020.
He was immediately loaned back to Grasshopper Club Zurich until the end of the season where he is enjoying first team football before heading to Goodison Park in the summer.
While there he has linked up with former Blues defender Senderos, who joined Grasshopper in January after leaving Aston Villa.
And he has now shared a picture with his compatriot on Instagram, describing him as his new English teacher.
Tarashaj will be hoping he can fare better at Goodison Park than Senderos did during his spell at the club.
Having signed on loan from Arsenal, he managed just two Premier League appearances all season as he proved to be one of David Moyes’ more forgettable signings.
Tarashaj certainly faces a fight for first team football when he does arrive, with the likes of Romelu Lukaku, Oumar Niasse and Arouna Kone all ahead him in the centre forward role at present.
