Italian football has always been extremely competitive, just think how variable the winner has been over the course of these decades, there are not like 2 teams like in Spain that dominate the Liga and very few can compete with them.
I don't know if you understand what i mean
The word extremely competitive may actually sound too strong and that is because technically the competition here is with a certain group of team about four of them or more so it is not like every other clubs in this league has keyed in so strongly with the competition, Juventus, Inter Milan, Napoli and Roma has been the highly competitive teams here, but sometimes we see AC Milan and Atalanta trying to come up but the vast majority are not as consistent as Inter Milan and Napoli recently. So even the competitiveness is actually recycled.
