While we still don't know if Mourinho will leave for Newcastle, the parts that are true right now is that Howe is not getting good results and could be sacked. In fact, if he was sacked right now, I wouldn't be shocked and that would fit perfectly for them, they are just not doing good enough. And with the amount of money they have now with the new owner, I believe they shouldn't be doing this badly, they were good for a short sting, went to UCL and all, but that was it, they have been bad ever since.
However, the mourinho part is that they just want a good manager and believing that they are doing good is the key, Mourinho could do good there, and everyone believes that, so it would not be a bad idea, not a must, they can find someone else too.
Newcastle need a manager like Jose Mourinho, Eddie Howe seems to have a hard time realizing the ambitious project of the new owner of The Magpies.
Of course there are many other options for the position of Newcastle manager in the future, if Eddie Howe is fired. But in my opinion, Jose Mourinho is one of the managers who should be considered to be recruited. In my opinion, Jose Mourinho still has bargaining power, he is not completely finished. If in the right environment, meaning with a team that has abundant financial support, it is likely that the Portuguese manager can still present trophies. In his managerial career history, Jose Mourinho was able to realize Roman Abramovich ambition at Chelsea in his first period, tt wouldn't be a bad idea for Newcastle to try their luck with him.
