Actually, with the current performance of Newcastle, in my opinion, Eddie Howe should feel threatened because in fact they are currently experiencing problems and crises in performance.
Newcastle have spent quite a lot to make their readiness in a good position and are considered one of the dangerous clubs in the last 2 seasons so it is certain that when the conditions are not in accordance with the desired expectations, the coach must be ready to bear all the decisions because it is certainly the coach who will be targeted because he is considered unable to advance the club.
Howe can get out of this trap if he is able to improve Newcstle's performance but if in the end he cannot do that then he must be prepared to leave.
