The young Swiss forward had to undergo knee surgery in Germany over the summer and the Liverpool Echo report that discussions were held about the possibility of sending him out on loan again but that he now looks set to remain with the Blues until the summer at least.
Tarashaj was the final signing of Roberto Martinez's three-year reign as Everton boss when he arrived from Grasshopper Zurich in a £3m deal but has yet to make his first-team debut.
He looked promising in pre-season in 2016 but was eventually loaned to Eintracht Frankfurt for whom he made 15 appearances, scoring once.
His hopes of breaking into the Toffees' senior set-up were dealt a severe blow when he suffered a serious knee injury last year and he has been in rehabilitation ever since.
The 22-year-old is now back at Finch Farm to complete his recovery where it's possible he could get a chance to impress for the Under-23s between now and the end of the season.
