Mourinho Next Everton Manager?
We will take a look at why it is the next possible step for Jose. Numerous times, Mourinho has claimed a certain respect for Everton fans, he’s even suggested that he would manage Everton in the past. What took Mourinho in at Chelsea was his love for the club and the fans, with Everton being a family club, he could look to build a great relationship with an extremely passionate set of fans. The Everton fans have fell out of love with Roberto Martinez after his recent run of results and “boring” football style.
Not a usual selection for Mourinho, however after this half season at Chelsea, he will look to jump back up and manager another club. There was large speculation that he would be managing Manchester United. Van Gaal has provided a bit of a resurgence there of late so it could very well be that he is given a little more time to prove he is right for Old Trafford.
This leaves Mourinho without large speculation against his name (although he will remain to be strongly linked to Manchester United). Everton only being on the other end of the East Lancashire Road, it could be a very attractive opportunity. Everton also have a fantastic team at present, it has even been suggested that it is the strongest squad Everton have had in a generation.
There is also some underground talk that suggests Farhad Moshiri has already had a conversation with Mourinho. Being a shrewd business man, Moshiri will know he will need to act with plenty of time to spare if he is going to pull off a coup as big as this. Everton need a game changer to push in the Premier League, this certainly would be it.
