Crucially, England’s Premiership, France’s Top 14 and the United Rugby Championship are open to playing their finals in May in order to accommodate the new tournament in June.
It is understood that the prospect of a strong commercial return for all stakeholders from the WCC has been key to the momentum behind establishing it in 2028.
A women’s version of the Champions Cup is planned for in 2026 with talks between the relevant leagues and unions to be held in June. This is expected to be limited to four European teams to begin with – the English and French champions, the winners of the Celtic Challenge (Ireland, Scotland, Wales) and the Latin Cup (Italy, Spain).
