James Rodriguez and Richarlison have been left unsettled by Carlo Ancelotti's resignation from Everton.
Earlier in the week Ancelotti was contacted by Real Madrid and left Merseyside within 48 hours after making it clear he wanted to return to the Spanish capital.
The Athletic reports now a number of stars are considering their futures, with the likes of Richarlison and James "particularly disillusioned as a result".
Many players made their feelings known with a small gesture of unfollowing the Italian boss on social media.
Ancelotti is one of the few managers in the world with a regular online presence, but in the hours following his stunning exit only James and Richarlison continued to follow his accounts online.
Everton had been preparing for a big summer under Ancelotti, with club chief Farad Moshiri having previously outlined a long-term project under the Italian.
