Euro 2020 is here.
The delayed European Championships will finally take place in June and July 2021 after being pushed back a year due to the Covid pandemic.
This summer's tournament will be held in various cities across the continent to help mark and celebrate the 60th anniversary since the first Euros.
It has also taken on different formats with the number of national teams competing at the finals increasing from eight to 16 at the same Euro 96 tournament.
Now, with the postponed Euro 2020 set to start, we take a look at how many nations will be competing this time around and what Euro 2024 may look like...
How many teams are in the Euros?
A total of 24 nations will compete at Euro 2020 this summer.
This is the same number of teams that qualified for the Euro 2016 tournament which attracted some criticism from Germany coach Joachim Low and defender Mats Hummels.
Germany were beaten by France in the semi finals but both Low and Hummels said the quality of the tournament wasn't up to its normal standards due to the increased number of teams.
Speaking to German broadcast company ZDF, Low said: "I think 24 teams are too many. The World Cup's going to be increased to 40 teams and it's getting more and more, and that's a problem in the long term.
"Sometimes you get the feeling it's not doing football any good. The quality is suffering."
Hummels said: "The level at this European Championship was not what we had hoped for. There were many teams who didn't want to do anything with the ball and just packed men behind the ball."
What is the Euro 2020 format?
It will see six groups (A-F) of four teams compete in three group stage matches before knockout football to decide the two teams to compete in the final.
The top two teams in each group will qualify for the knockout stage along with the four best third placed finishers, meaning eight teams will go home after the groups.
A Round of 16 will determine who makes it through to the quarter finals, with the winners reaching the semi finals and the winners of the last four games will play the final.
Who are the teams competing at Euro 2020?
Group A: Italy, Switzerland, Turkey, Wales
Group B: Belgium, Russia, Denmark, Finland
Group C: Ukraine, Netherlands, Austria, North Macedonia
Group D: England, Croatia, Czech Republic, Scotland
Group E: Spain, Poland, Sweden, Slovakia
Group F: Germany, France, Portugal, Hungary
What will the Euro 2024 format be?
The expanded tournament has faced some criticism but is part of UEFA's vision for the future of the European Championships, which could see 32 teams compete at some stage.
UEFA officials keep the format under review, with the general secretary Theodore Theodoridis saying: "I am confident that we have more than 32 very competitive teams in Europe."
And added: "But a format of 32 would kill the qualifiers so it is balance, you have to consider a little bit of everything."
The next Euros, in Germany in 2024, will see 24 nations again compete with the same format of top two and four best third placed finishers advancing from the group stage.
