Maurizio Sarri said that the biggest difference between the Premier League and Serie A was in the number of sprints per match.

Sarri also distinguished between the quality and quantity of running, saying that while Serie A players run more, Premier League players run with more intensity. 

“In Italy, we run more in terms of quantity. But the difference is the quality. Here, there are more accelerations and the number of them is really very important. There are 1.1 accelerations every minute – over 23, 24 kilometres per hour – and it’s difficult because for these accelerations, you need a very big engine. It is more difficult than in Italy. The quantity of running is higher in Italy or at least the quantity of running of Napoli was more than at Chelsea but the quality is different.”
