Right now we are better on the pitch than the EPL clubs because we are managed very efficiently + because football involves a lot of variables that need to be done right for a squad to fulfill its potential. These variables include the coach's ability, the scouting, the players' form at key moments in the season, the club environment and so on. We get these non-financial variables right and so it offsets our financial disadvantage. The richer EPL clubs are managed very inefficiently wasting money right and left and their coach hirings havent worked out so far so they are not getting the non-financial variables a lot.
The fear is not just that the financial gap is big, the fear is that it is consistently getting bigger at an alarming rate and it seems that this trend will continue for years. Their relative inefficiency won't matter in the long run the bigger that gap gets. Our efficiency can bridge a gap up to a certain point afterwhich we will be too priced out in the market even when it comes to buying youngsters. Whats even worse, sooner or later the richer clubs will get the non-financial variables right even if its by trial and error. They will keep pouring money on their problems until it is fixed and at this point we will be left behind. They have already acquired every top coach there is around and they will do the same with scouts and players and so overtime the financial gap will be reflected on the pitch.
Juve needs some serious CL performances in the next few seasons so that the gap stays the same and we continue to have a shot. To shrink the gap we need Serie A to become competitive again which sadly wont happen anytime soon. Berlu selling Milan can be a good start.
