The short version

  • In the EuroLeague, Greek clubs win 60.1% of games against clubs from other leagues, the best record of the 9 leagues there. That is Olympiacos and Panathinaikos.
  • In the EuroCup, Greek clubs win 34.6%, second from bottom of 12. In the Champions League they win 46.3%.
  • In the Greek league, Olympiacos and Panathinaikos beat the other clubs 95.0% of the time, by 18.4 points a game. None of the other eight leagues here is that one-sided.
  • Spanish clubs win at least 58% in all four European competitions. No other league wins more than half in all four.
  • This season the Greek middle has started well: 22 wins from 34 games below the EuroLeague. It is early.

How strong is a league? Look at what its clubs do when they leave home. Every season, clubs from a dozen countries meet in four European competitions. Count only the games between clubs from different leagues and each league gets a record against the rest of Europe.

Greece's record splits in two. At the top it is the best in Europe. In the EuroCup it is near the bottom.

Greek clubs' win share against other leagues, by season. A competition with fewer than 8 such games in a season is left out. 2015-16 and 2019-20 are missing: too few EuroLeague games.
The EuroLeague clubs pulled away from 2023-24

In each of the last 3 seasons Greek clubs won between 65.1% and 66.7% of EuroLeague games against other leagues. Below the EuroLeague, they won less than half in 9 of 13 seasons. The clubs below did as well or better only in 2018-19, 2020-21 and 2022-23.

What it means

The two big clubs grew stronger. The rest of the league did not follow.

6. Our own record: does Pythia rate the Greek clubs right?

Our forecasts made before each European game against another league, 28 October to 9 November 2026.

Before each game our model gave each club a chance of winning. For Greek clubs against other leagues it averaged 61.8%; for Spanish clubs 66.9%.

Greek clubs: 11 games. Spanish clubs: 15 games. Far too few to judge.
So far, Greek clubs have done better than we expected

They won 72.7% of 11 games; we expected 61.8%. Spanish clubs won 60.0% of 15; we expected 66.9%. Two weeks of games can swing this far by chance.

What it means

We publish this every day, good weeks and bad. See how we score ourselves.

Is the Greek middle catching up? This season Greek clubs below the EuroLeague have won 22 of 34 games against other leagues (65%): Aris 5 of 6; PAOK 4 of 6; Peristeri 3 of 3; AEK Athens 2 of 3. In the last five seasons they won 44.8%. A few weeks is not a season. We will check again when the group stages end.

How we count. Finished European club games, regular season and playoffs, in the EuroLeague, EuroCup, FIBA Champions League and FIBA Europe Cup, including qualifiers. A club belongs to the domestic top flight where it played most games that season; Adriatic clubs that play the ABA League count as ABA. Only games between clubs from different leagues count. A league needs 30 or more games in a competition to be shown. Clubs from the VTB League played only part of 2021-22 in this window and are left out. A league's record depends on which of its clubs went to Europe, so it measures those clubs, not every club in the league. Causes are offered as questions, not facts.
