Olympiakos Piraeus vs NEC Nijmegen Preview: Champions League Qualifying First Leg

Two clubs with vastly different European pedigrees collide at the Georgios Karaiskakis Stadium on Tuesday, 4 August 2026, as Olympiakos Piraeus vs NEC Nijmegen opens the first leg of their UEFA Champions League Third Qualifying Round tie. For Olympiakos — 48-time Greek champions and seasoned European campaigners — this is a familiar stage. For NEC Nijmegen, it is a historic occasion: the Gelderlanders have never reached the group stage of the Champions League, and their presence here is the reward for a sensational 2025/26 Eredivisie campaign. The stakes couldn't be higher. Whoever advances over two legs earns a place in the Champions League Play-Off Round, one step from the richest competition in club football.

Match Overview

This fixture is part of the UEFA Champions League Qualification Semi-finals bracket , with the winner of the two-legged tie progressing to the Play-Off Round. Olympiakos Piraeus vs NEC Nijmegen takes place on Tuesday, 4 August 2026 with kick-off at 18:00 local time at Georgios Karaiskakis Stadium.

Olympiakos, a 48-time Greek champion, ended last season trophyless, finishing second in the league, six points behind AEK Athens. Motivated to reassert themselves on the European stage, they enter as the bookmakers' favourites. During the offseason the club has been super-active, adding 11 players in total, with arrivals carrying a combined market value of around €61 million.

The tie also has a modest head-to-head footnote worth noting: these teams have met just once in their history — a 2024 friendly in the Netherlands — which Olympiakos won 2-0. That result offers little predictive weight, but it confirms the Greeks have already shown they can handle NEC when the sides meet.

Olympiakos Piraeus Form & Recent Results

Olympiakos have been in solid form recently, winning 2 of their last 5 matches. They have scored 6 goals and conceded 4 during this period, conceding an average of 0.8 goals per game. The headline numbers are respectable, but the pre-season context raises questions: Olympiakos lost their last three pre-season friendlies heading into this qualifier.

Olympiakos's recent pre-season schedule included a 3-2 loss to AZ Alkmaar, a 3-0 defeat to Royal Antwerp, a 1-0 loss to Ajax, a 3-1 win against Fortuna Sittard, and a 1-1 draw with Oud-Heverlee Leuven. The three consecutive losses to Dutch and Belgian opposition are a concern, though it is worth noting that pre-season results — particularly against clubs already mid-season — are an imperfect gauge of a team's readiness.

Last season, Olympiakos scored an average of 1.59 goals per game while conceding just 0.53 — a formidable defensive record in the Greek Super League. Their home fortress at Karaiskakis is a genuine advantage: the atmosphere there is renowned, and Olympiakos are significantly more difficult to break down on home soil. Goalkeeper Stefan Ortega, who arrived from Nottingham Forest on a free transfer, will not be available, as he was not registered for the Champions League Qualifiers and is not yet physically fit.

NEC Nijmegen Form & Recent Results

NEC finished third in the Eredivisie last season — a genuine surprise — and earned a spot in the qualifying rounds of Europe's top club competition. They also reached the Dutch Cup final, where they fell to AZ Alkmaar, losing 1-5. Under coach Dick Schreuder, NEC deployed an attack-minded 3-5-2 system throughout 2025/26, posting impressive numbers.

The Dutch side played in a much more entertaining style than Olympiakos last season, scoring an average of 2.26 goals per game but conceding 1.56 per match. In 75.6% of their matches the total goals were over 2.5, and in a remarkable 95.1% of games the total was over 1.5 goals. Bettors who favour high-scoring encounters should take note.

Their pre-season results, however, have been a mixed bag heading into this qualifier:

NEC lost their final pre-season rehearsal against Sevilla 1-2, with Sami Ouaissa having put Nijmegen ahead before the Spanish side came back to win. Dick Schreuder's side can now focus fully on Tuesday's Champions League qualifying match.

Despite the patchy friendly results, NEC's attacking style through a 3-5-2 formation with swift flank attacks represents a genuine threat to any opponent. Key concern: winger Basar Onal departed to Lille for €12.5 million during the offseason, though the club reacted by adding Dusan Tadic as a replacement. Striker Koki Ogawa is also not registered for this qualifier, and with no official injury reports, a departure may be imminent.

Team News & Possible Lineups

Olympiakos Piraeus

Olympiakos have been one of the busiest clubs in Europe this summer. The club added 11 players during the offseason , including Mehdi Taremi (forward) and Clayton (striker from Rio Ave). The squad is deep and refreshed, but there is at least one notable absentee for this opening leg.

Key absences & doubts:

• Stefan Ortega (GK, ex-Nottingham Forest) — not registered for the Champions League Qualifiers; still not physically fit to play.

Expected XI (4-3-3): Tzolakis (GK) — Rodinei, Cisse, Neto, Myto — G. Martins, Hezze, Camara — Strefezza, Taremi, El Kaabi. (Note: exact lineup not yet officially confirmed; based on available squad information.)

NEC Nijmegen

Nijmegen are set to field their strongest possible lineup as they face Olympiakos in the Champions League qualifiers. The squad underwent significant changes in the offseason. Dusan Tadic should be the perfect replacement for the departed Onal, bringing his vast European experience to NEC's attacking line.

Key absences & doubts:

• Koki Ogawa — not registered for the qualifier; likely departure pending.
• Injuries are making things difficult for NEC ahead of this trip.

Expected XI (3-5-2): Crettaz (GK) — Dasa, Kaplan, Fonville — Ouaissa, Sano, Nejasmic, Chery, Lebreton — Tadic, Linssen. (Note: lineup not officially confirmed; inferred from recent match data and squad updates.)

Prediction

Betiball does not accept bets. All examples and predictions are for educational purposes only.

The market paints a clear picture: Olympiakos are expected to win at home, priced at odds of around 1.60, while NEC lost four out of their pre-season friendlies heading in. Home advantage at Karaiskakis is genuine — the Piraeus ground is notoriously hostile — and Olympiakos's defensive solidity from last season (0.53 goals conceded per game) makes them difficult to break down on their own patch, even for a free-scoring Dutch side.

Tactically, the contrast is striking. Olympiakos are likely to be compact and patient, looking to exploit set-pieces and transitions. NEC, by contrast, favour an aggressive 3-5-2 with swift flank attacks that has produced high-scoring games throughout their Eredivisie campaign. In 34 of their matches this past season, both teams scored — a trend that is hard to ignore. If NEC's press opens spaces, Taremi and El Kaabi could punish them on the counter. But NEC's work-rate and pressing game means Olympiakos cannot afford to sit too deep.

With both teams carrying some pre-season rust — both clubs arrive after poor friendly sequences, with Olympiakos losing their last three and NEC losing their past two going into this game — goals at both ends look likely in what should be a cagey but open first leg. The home advantage and the class of a refreshed Olympiakos squad narrow the gap, but NEC are no pushovers. Betiball's read: Olympiakos Piraeus to edge the first leg 2-1, setting up a tense second leg in Nijmegen on 11 August.
