The next appointment has to be thought out and planned. We can't just rush into "anyone but Allegri", it is not going to solve problems and we'll be in the same position in a year's time unless we get lucky by finding the right coach.
Manchester City spent a year preparing everything for Pep to to arrive. And even then, they were pretty bad in his first season.
Klopp was nothing special for Pool in his first two seasons either.
And here we except our coaches to succeed from day one, despite not having a coherent plan for building the team.
Nothing I’ve seen from Allegri so far suggests we will get much better. I dont even see the hunger and motivation to win every game- something which was always there in his first stint. So yes, it’s not the worst decision to let him go, but we shouldn’t do so unless we have a good name lined up to replace him.
