Ancelotti is not a manager who favors ball possession, but who likes his teams to be more direct. Of course there are nuances here, but even in Real Madrid he favored a more direct style. They played counter-football, which he was eventually criticized for. So I can hardly imagine him starting to implement it at Everton.
I will not criticize Ancelotti for the results. Considering the injury situation, we have taken a lot of points, which I agree with you. But I think we have also been extremely lucky with the results. What I am more skeptical of, and here I hope I am wrong, is that with this type of football we have reached the ceiling. With this type of football, we have not laid any foundation that we can develop further next season. In many ways, we have sacrificed long-term success for short-term "success". The same can be said about player logistics.
This is where I think Leicester have done a lot right. They have acknowledged that they can not compete with the big clubs financially, and must therefore have a completely different model. They have a clear football philosophy, and allow players to develop within this framework. They have a clear and distinct player logistics, and buy players who are mostly in the right age group, develop them, and sell them expensively.
Since they have a manger with a clear football philosophy, they also know what types of players they want and how they can use them and develop them. If, for example, we had brought a similar player like Tielemans (who was not such a good football player in Monaco) to today's Everton, do you think he would have been a success?
