A recent win over Burnley has temporarily eased concerns about his job security, but there are still doubts about his suitability for the role.
Some players are unhappy with Amorim's strict tactics and formations, which they feel are not well-suited to the Premier League.
Additionally, some players are upset by public criticism they received from Amorim, particularly after a recent defeat.
There are also concerns within the board about Amorim's attitude and his claims that he has considered leaving the club since his arrival.
