Yeah we somewhat have too many defenders. We can't place them all in the starting 11 anyway.
Thinking about it now we have to use something that will finally work. If we fail to qualify in CL we won't really have money to buy new players that Conte will surely request in the summer. We'll be forced to sell if we continue like this.
After all it's obvious why we play 3 man defense and 3 man midfield. We've come to the point we can't really deploy both of Pirlo and Bonucci. We benefit very little lately from their presence on the pitch. I think having one of the two is OK.
Changes are needed. We need new ideas and new tactics. Current ones are already known by our opponents they know how to play against us very well.
