Uefa Cup given new name in revamp
The new-look league will have 48 clubs in 12 groups of four, with teams playing each other home and away as opposed to just once as it stands now.
The top two in each group then join the eight third-placed Champions League clubs in a 32-club knock-out stage.
However, under the new format beaten cup finalists will no longer qualify for the competition.
Millwall and West Ham have both qualified as beaten FA Cup runners-up in recent years, but Uefa says this will no longer be the case, even if the winners have already qualified for the Champions League.
The competition will also have its TV rights sold centrally, in the same way as the Champions League, which should increase income to clubs.
