Guidolin feels the campaign is now too packed.
The coach said: "I have become accustomed to working at a frantic pace for 20 days, followed by a spell with very few players at my disposal. Until there's a new rule to stop this system, it'll be difficult to have everyone at their best. Unfortunately, when the decisions are made by others, you have to accept and adapt.
"I like the idea of an 18-team Serie A, as there are players here who will take part in 16 games from now to Christmas. In the past 16 games was half a season. If you add internationals, then you have the equivalent of half a Serie A season squeezed into two months. Does that seem logical to you?"
