In Serie A, from time to time, some middle-class clubs can start a good season, not so long ago in Serie A there was a Chievo club, they could also have a promising start, but then there was always a decline. I don’t see how Udinese will be able to last the whole season, although the example of Leicester (when they won the Premier League) shows us that nothing is impossible. So far, Udinese is Serie A dark horse this season.
Yes, it's true the mid-table teams initially put on an outstanding performance at the beginning, but the consistency has become the real problem that is often encountered. This is normal in football. Although I also don't deny that maybe what Leicester success in EPL few season back have achieved is experienced by Udinese and becomes champions, then this will be an extraordinary season for Serie A.
