Europe's leading clubs will try to derail Uefa plans to give Champions League places to domestic cup winners later this month.

Uefa's president, Michel Platini, has pledged to increase the number of league champions from mid-size countries in the group stage of the Champions League, a commitment that requires a reduction in the representatives qualifying from Europe's "big six" leagues.

Platini's plan is to establish a play-off system for domestic cup winners from 16 countries, with four progressing to the group stage. Six places would be made available to the champions from countries ranked 13 to 52 by Uefa who would qualify through a separate competition.

The remaining 22 places would be made of up of teams from major nations, all of whom would qualify automatically. This would increase the number of champions from the current minimum of nine to 18. In England the top three clubs in the Premier League would qualify with the FA Cup winner entering a two-round play-off.

The plans are due to be discussed at a meeting of Uefa's professional game strategy council on November 12. Meanwhile, the G14 chief executive, Thomas Kurth, played down threats of a boycott of the competition: "We are not in favour of a boycott or a breakaway, but the clubs are not happy with the changes put forward and we want to be listened [to]."
