Portugalete vs R. Union Prediction & Betting Tips (18 November)

Copa del Rey first-round football finally comes to Estadio La Florida on Wednesday 18 November 2026, when fourth-tier Club Portugalete host third-tier Real Unión Club in an all-Basque Country tie with a place in the round of 32 at stake, where the La Liga giants enter the competition. It has been a long road to get here: the tie was drawn on 5 October, was originally scheduled for Wednesday 28 October, and was then suspended by the RFEF out of respect and solidarity following the tragic train accident in Toledo, before being reprogrammed first for 4 November and then for this midweek November date, with Alfredo Ramo Andrés appointed as the referee. History between these two neighbours dates back more than two decades — AiScore records eight meetings since 2005, with Real Unión holding a narrow 4-3 edge in wins and one draw, including a 1-0 Copa del Rey second-round victory at La Florida back in September 2005, a tie sandwiched between a 2-0 Portugalete league win days later and a 5-0 Real Unión triumph in Irun in February 2006. They also met in a friendly in August 2025, so there is genuine familiarity despite the two divisions now separating them on paper. The market reflects how finely balanced this one-off cup tie is: European odds of 3.15 for a Portugalete win, 3.30 for the draw and 2.35 for a Real Unión victory in 90 minutes, with the visitor’s superior divisional status only modestly respected by the bookmakers.

Club Portugalete arrive at their biggest night of the season on the back of a dream start to life back in the Segunda Federación. The gualdinegros won the 2025-26 Tercera Federación title to earn promotion, and Egoitz Bilbao’s squad have carried that momentum into the fourth tier, sitting sixth in Group 1 with 16 points from ten games (four wins, four draws, two defeats, 15 scored and 12 conceded) and in the promotion play-off conversation. After early defeats to Bergantiños (3-2 away) and Alavés B (2-0 at home), Portugalete are unbeaten in four league matches: a 2-1 win at Amorebieta, a goalless home draw with Eibar B, a 2-2 stalemate at Basconia and a 3-3 thriller against Arosa — evidence of a side that is hard to beat but has kept only two clean sheets. The club moved quickly to keep the spine of the promotion side together, confirming renewals for captain-goalkeeper Ibón González, midfielder Yeray Cuello and attackers Alain Lete and Gorka Tapiador for 2026/27, while the squad around them blends experience and youth: Kevin Ríos and Unai Llorente compete in goal behind a defence featuring Gonzalo Alfaro and Anartz Amilibia; Iñigo Arzuaga, Ibai Quintana, Iñaki Bilbao, Javier Elías Estebas, Iván Del Campo, Unai Lechosa and Uztaritz Expósito supply the midfield legs; and the forward line is led by Xabi Cortezón, Xabi Gómez, Alex Pérez, Unai Garcés, Gorka Crespo and Anartz Rementería, a group that has shared goals around rather than relying on one marksman. A packed La Florida, with members given priority in the advance ticket sale, will give Portugalete the emotional fuel typical of Copa nights in the Basque Country.

Real Unión, by contrast, are a historic Irun outfit now plying their trade in the third-tier Primera Federación, and their season has been a story of fine margins under head coach Iñaki Goikoetxea. The txuribeltz sit 13th in Group 1 with 13 points from 11 matches (three wins, four draws, four defeats, 19 scored and 19 conceded), and their recent form curve is a concern: after a superb 4-1 home dismantling of leaders Lugo on 23 October — their best result of the campaign — they have lost back-to-back league games, beaten 3-0 at home by Avilés and then defeated at Barakaldo, meaning they have won just one of their last five. There is, however, genuine quality in the 2026/27 squad. Summer signings Aitor Galarza, arrived from Eibar, and Yassin Tallal, from Getafe, were designed to add a cutting edge, and Galarza has delivered with five league goals to lead the club’s scoring charts, followed by Ekain Azkune on three and experienced playmaker Luca Sangalli on two. Between the posts Jon Tena remains the reliable reference point, with Lander Emery as deputy; the defence is built around Jordi Pola, Paul Álvarez, Odei Rodríguez, Hugo Carrillo, Manolo Molina, Javi Fontán and Álvaro Mateo; the midfield boasts Ángel Montoro, Asier Salcedo, Eneko Romo, Markel Robles, Beñat Gaubeka and the creative Martín Arruti; and Galarza, Azkune, Tallal, Santi Miguélez and Ignacio Tellechea give Goikoetxea several routes to goal. For a club of Real Unión’s tradition, the Copa del Rey is also a welcome distraction from a stuttering league campaign — and an away tie at a fourth-tier neighbour is precisely the kind of fixture a third-tier favourite is expected to navigate, even if their away form (winless in their last two on the road) tempers that expectation.

Our prediction is a narrow 0-1 away win for Real Unión — a scoreline that would send the txuribeltz into the round of 32 while keeping Portugalete’s battling cup run alive until the final whistle. The logic is straightforward: Real Unión’s squad, assembled with second-tier and top-flight academy pedigree, operates a full division higher, and in Aitor Galarza they possess the one genuine match-winner on the pitch, a striker who scores roughly every other game this season. Data-driven models agree with the direction if not the margin: Sports Mole’s algorithm makes a Real Unión win the single most likely outcome at 37.2%, with 0-1 the most probable away scoreline at 8.85%, just ahead of 1-2 and 0-2, while a draw (25.9%) and a Portugalete win (36.9%) are both live possibilities at a venue where the hosts are unbeaten in four. Expect a tight, tactical Basque cup tie rather than a goal fest — the modelled goals markets sit almost exactly on the 2.5 line (Over 2.5 at 52.49%, Under at 47.51%) and Both Teams to Score at 53.4% — so the value angles point the same way as the prediction. Our betting tips in European odds: Real Unión to win at 2.35; Under 2.5 goals at 1.90; Real Unión to win to nil at 3.10; Aitor Galarza to score anytime at 2.60; and the correct score 0-1 at 11.00. In a match defined by patience and one moment of quality, we expect Galarza — or a set piece from Sangalli’s delivery — to provide that moment, and for Portugalete’s brave promoted side to fall just short of a famous upset at La Florida. Final score: Portugalete 0-1 Real Un
