Olympiakos hosts Sparta Prague with unbeaten record and group lead on the line

Olympiakos arrives at Georgios Karaiskakis Stadium with a perfect record and plenty of motivation to stay near the top of the Europa League's league phase. Standing in the way is Sparta Prague, also unbeaten but with a draw mixed in, in a matchup between two sides fighting to remain among the tournament's best.

Olympiakos has racked up two wins in two matches in the competition, with three goals scored and one conceded, and arrives on the back of five straight victories across all competitions. That run has the club sitting tenth, with 6 points, though it's worth not reading too much into the standings just yet: only two matchdays have been played, and goal difference still carries more weight than the exact order of the table.

Sparta Prague, for its part, is also unbeaten: one win and one draw in the tournament, with five goals scored and two conceded, leaving it in eleventh place with 4 points, just two behind the home side based on the points gap between them. Over its last five matches in all competitions, the sequence has been a bit more uneven: three wins, one draw and one loss, painting the picture of a competitive side, though not quite as solid as the Greek club has been in this early stretch.

As for the season's trends, some caution is warranted about what they really mean: in the 2026 Europa League, home and away combined, Olympiakos has kept a clean sheet in 50% of its matches and tends to score most often between the 31st and 45th minutes, with Armando Gonzalez, Santiago Hezze and Roman Yaremchuk as its top scorers in that sample. Sparta Prague, in that same competition and season, has yet to keep a clean sheet in any match within that sample and tends to score between the 16th and 30th minutes, with Tobias Guddal its top offensive threat with two goals, followed by Josimar Alcocer and Patrik Vydra. These figures come from a separate sample and shouldn't be confused with each team's record so far in this tournament.

Probable lineups

For Olympiakos, managed by Imanol Alguacil, the expected lineup features Stefan Ortega in goal and a back line that could include Panagiotis Retsos, Lorenzo Pirola, Nayef Aguerd, Marcus Pedersen, and Manolis Saliakas. In midfield, Remo Freuler, Gustavo Puerta, Chiquinho, Jota Silva and Konstantinos Fortounis could all feature. This lineup is projected from recent matches with medium reliability, so it should be taken as an approximation.

Sparta Prague, led by Brian Priske, could line up with Jakub Surovcik in goal, a back line of Adam Sevcik, Martin Suchomel, Matej Rynes and Asger Sorensen, a midfield of Andy Irving, Hugo Sochurek, Roman Macek and Adam Karabec, and John Mercado alongside Jonatan Braut Brunes up front. In this case, the reliability of the projection is low, so there's more room for surprises in the Czech side's starting eleven.

What the numbers say before kickoff

Our model gives Olympiakos a degree of favoritism, though not by an overwhelming margin: there's real room for any result.

A 52% probability for the home side against 18% for the visitors leaves the draw, at 30%, as a possibility that can't be ruled out. These figures come from our own estimate based on the season's trends, not a betting line or a definitive forecast, but they do suggest Olympiakos starts as the favorite without making Sparta Prague any less of a threat.

With both teams unbeaten and fighting to stay in the upper half of the league phase, the match at Georgios Karaiskakis Stadium promises to show just how far each side can go in this edition of the Europa League.
