UEFA intends to stick with 24 teams for Euro 2020 despite criticism about the format this year.
Four third place teams joined the winners and runners-up to form a round of 16.
"The decision has been made to go for 24 and all the preparations for 2020 are with 24 teams," UEFA general secretary ad interim Theodore Theodoridis said, when asked if it could go back to 16 teams or even be expanded to 32.
"But this particular committee is constantly reviewing the different elements and comes with proposals.
"But for 2020, we will go for 24. For 2024, it is wide open and it will be a proposal that is a very interesting discussion because there are pluses and minuses for every format.
"We have to see the overall picture of the competition -- not only the final tournament but also the qualifiers.
"If you ask me about 32, I am confident that we have more than 32 very competitive teams in Europe.
"But a format of 32 would kill the qualifiers so it is balance, you have to consider a little bit of everything."
