Italian players association president Damiano Tommasi has announced a strike will delay the scheduled start of the Serie A on Saturday.

All 20 Serie A captains signed a document this month threatening a strike if a new collective contract was not signed before the season opens, and weeks of negotiations produced no resolution.

The main conflicts are over two clauses the clubs want - one that would allow them to force unwanted players to train away from the first team and another that would make players pay a new government solidarity tax that applies to high-wage earners.

With a break for international matches over the weekend of Sept. 3-4, the strike could delay the start of the season until Sept. 10-11 - or beyond.
