Since the teams in Serie A and the teams in the Premier League are very close to each other in power, the race is always fierce. Apart from the great league victory of Napoli this year by big points, there was a great Serie A Scudetto race last year. However, there is another truth. If the strength of the teams in Serie A is 70, the strength of the teams in the Premier league is 80. So the Premier league is slightly higher on average. This is also a fact.
Such facts are really visible this year, but I hope that there will be a more significant balance and improvement next season for the teams in Serie A. Because when the forces are balanced, the competition will definitely be much fiercer than before which thing This can be seen clearly when teams in Serie A compete against teams in the Premier League in the UCL competition and the European League. Meanwhile, the comparison of their strength is taken from their appearance in their own domestic league, I think it will not be very accurate.
I think if forces are equal so teams are on similar power level I think Italian team would win most of those games. Italian teams were always better with strategy and know how to expose other teams. We saw that in CL finals this year, City is much stronger then Inter but in one game Inter almost pulled out a surprise.
