FIFA and UEFA are at loggerheads over plans to resume international football with the world governing body seeking a radical overhaul of the calendar beginning with an extended window for matches at the end of the year.
Sportsmail has learned that FIFA are proposing the creation of a long international break, in which national teams could play as many as eight games in November and December.
If introduced, this would see England play all their UEFA Nations League fixtures — and possibly some friendlies — in a single block of matches.
FIFA are seeking to create a global solution to the scheduling problems caused by the coronavirus pandemic, which has decimated international football over the last few months.
In addition to the postponement of Euro 2020 for 12 months, this summer's Copa America and the start of qualifying for the 2022 World Cup have been put on hold, and international breaks scheduled for September and October are also under threat because of the growing likelihood that the start of domestic club seasons will be delayed.
FIFA's proposal is based on attempting to restart the international game while also giving more space for club football next year.
It is understood FIFA are willing to sacrifice the international breaks planned for September, October and another one scheduled for next March in return for creating a bumper window lasting several weeks in November and December.
England have six Nations League matches home and away against Belgium, Denmark and Iceland scheduled for this autumn.
If the new window is created, these games could all take place during that period in a mini-tournament.
UEFA have yet to give their support to FIFA's plan, however, as they are particularly reluctant to sacrifice next March's international window.
Although there is a growing acceptance that the September window will have to be scrapped, UEFA's preference is to create two slightly larger breaks in which nations would play three games in October and November, as previously reported by Sportsmail.
FIFA are opposed to this solution, however, as the travel distances for countries outside Europe will not permit three games to be played within a two-week period which has led them to propose one large window.
UEFA are resisting pressure to scrap the Nations League despite the complication of scheduling the finals in the same year as the European Championship.
In a congested summer, the Nations League finals are currently due to take place from June 2-6, with the European Championship starting on June 11 and the Under 21 tournament on June 9.
