2015 Copa del Rey Final

Aritz Aduriz scored five goals in Athletic's progression through to the final

Athletic Bilbao, of La Liga, entered in the last 32 against a Segunda División B team, Alcoyano. In the first leg away at the Estadio El Collao on 2 December 2014, they drew 1–1; Francis opened the scoring for the hosts while Borja Viguera equalised in added time.[11] Sixteen days later at the San Mamés Stadium, Viguera's first-half strike was enough to win the match.[12]

In the last 16, the club faced top-flight club Celta Vigo, and began with a 4–2 away win at the Galician club's Balaídos on 6 January 2015. Defender Mikel San José headed Athletic into an early lead, only for Álex López to equalise for the hosts six minutes later, and Aritz Aduriz to restore the visitors' lead four minutes after that. In the second half, Charles made it level again, but a Markel Susaeta goal and a late penalty from Aduriz gave Athletic the win.[13] Celta won the second leg 2–0 via a Xabier Etxeita own goal and a Fabián Orellana contribution, but Athletic advanced on the away goals rule.[14]

Athletic's quarter-final began on 21 January with a goalless draw at the La Rosaleda Stadium against Málaga, but eight days later in the second leg Aduriz scored three minutes into the second half to send them into the semi-finals.[15] The semi-final against Espanyol began with a 1–1 home draw, Aduriz putting Bilbao ahead on his 34th birthday and Víctor Sánchez equalising ten minutes before half time.[16] On 4 March, Athletic travelled for the second leg at the Estadi Cornellà-El Prat and won 2–0 to reach the final, with first-half goals from Aduriz and Etxeita.[17]

Pedro scored a hat-trick in Barcelona's 8–1 win over Huesca in the last 32

Barcelona, also of La Liga, entered the tournament in the last 32 against a Segunda División B club, Huesca. The first leg was in Aragon at the Estadio El Alcoraz on 3 December 2014, and Barcelona won 4–0 with goals from Ivan Rakitić, Andrés Iniesta, Pedro and Rafinha.[18] Due to the large advantage, Barcelona rested key players for the second leg but nonetheless won 8–1 for a 12–1 aggregate. Pedro scored a hat-trick among further goals from Sergi Roberto and Iniesta for a 5–0 half-time lead, while Adriano and substitutes Adama Traoré and Sandro Ramírez added more goals in the second half; Carlos David scored a late consolation for the visitors.[19]

In the last 16, Barcelona met top-flight opposition in the shape of Elche, but won 9–0 on aggregate. They hosted the first leg at the Camp Nou on 8 January 2015 and won 5–0, with two goals from Neymar, a Lionel Messi penalty and contributions from Luis Suárez and Jordi Alba.[20] A week later at the Estadio Manuel Martínez Valero, Barcelona defeated the Valencian club 4–0, starting with a free kick from defender Jérémy Mathieu followed by a long-range strike by Roberto, a penalty by Pedro and an added-time goal by Adriano.[21]

On 21 January, Barcelona hosted the first leg of the quarter-finals, and defeated Atlético Madrid 1–0. Sergio Busquets was fouled, giving Barcelona a late penalty. Messi took it and it was saved by Atlético goalkeeper Jan Oblak, but Messi scored the rebound.[22] A week later at the Vicente Calderón Stadium, the hosts made the aggregate score level in the first minute through Fernando Torres; in the ninth minute, Neymar put Barcelona back into the lead. When Javier Mascherano fouled Juanfran, Raúl García's penalty gave the advantage back to Atlético, but Barcelona scored two more goals in the first half from a Miranda own goal and Neymar to win 4–2 on aggregate. Atlético captain Gabi was sent off at half time for arguing with the referee, and his midfield partner Mario Suárez was also dismissed later on.[23]

Barcelona hosted the first leg of their semi-final on 11 February, and defeated Villarreal 3–1, with a half-time lead from Messi. Within the first five minutes of the second half, Manu Trigueros equalised with a long-range strike but Iniesta gave the advantage back to Barcelona, which was extended by Gerard Piqué later on despite Neymar missing a penalty.[24] They won by the same scoreline again in the second leg at the Estadio El Madrigal on 4 March with a brace from Neymar and a goal by Suárez, despite former Barcelona player Jonathan dos Santos equalising at one point.[25]

Athletic kicked the game off, and had an opportunity after five minutes, when Mikel Rico crossed for Aduriz, but he was prevented from making contact with the ball by Jordi Alba. Five minutes later, Barcelona launched a counter-attack starting with goalkeeper Marc-André ter Stegen and ending with Neymar volleying the ball into the goal, but it was ruled out for offside. Soon after, Iago Herrerín saved from Messi. In the 20th minute, Messi scored the first goal of the game, taking possession on the right-hand side of the pitch and beating four defenders before finishing with a near-post shot. Barcelona had more chances after this, with Herrerín making saves from Neymar. In the 36th minute, Neymar scored the second goal of the game, finishing from close range when set up by Suárez, after earlier work by Messi and Rakitić. Near the end of the first half, Andoni Iraola set up Iñaki Williams, whose volley missed the target. Piqué and Iraola received yellow cards at the end of the first half, for fouls on Aduriz and Suárez respectively.[26][27]

Ten minutes into the second half, Andrés Iniesta was substituted for Xavi, who took over as captain for his 766th Barcelona appearance, and last one at the Camp Nou. Soon after, Athletic substituted Iraola in his final match, replacing him with Susaeta, while Mikel Balenziaga was booked for his foul on Messi. In the 74th minute, Dani Alves co-operated with Neymar before setting up Messi to put Barcelona 3–0 up. Six minutes later, Athletic gained a consolation goal from Williams' header. In the closing stages of the game, Neymar showboated around opposition players, and was pushed over by Unai Bustinza, starting a melée between both sets of players. After play restarted, Neymar received a yellow card for fouling Balenziaga. In added time Susaeta fouled Neymar, and Busquets was booked afterwards for dissent; the foul earned a free kick from which Xavi hit the post.[26]

The conduct of Barcelona forward Neymar was debated by both teams after the final

The conduct of Neymar, who performed tricks with the ball in the closing stages of Barcelona's victory, was a talking point after the match. His opponent Iraola decried Neymar, saying that his actions were unsporting, while Barcelona manager Luis Enrique said that Neymar's actions were common in Brazil, even though frowned upon in Spain, and would have to change. However, Neymar himself did not apologise and said that he would repeat his behaviour in the future.[28]

In July 2015, the Spanish Sports Council levied fines against both clubs and the RFEF, with all three entities deemed to have taken insufficient action against security breaches and planned protests of Basque and Catalan separatist supporters who jeered the Spanish national anthem and King Felipe VI. Barcelona were laden with a €66,000 fine, Athletic with €18,000 and the RFEF €123,000. Barcelona claimed that the fines were punishment of freedom of expression.[29]

Lionel Messi's first goal was nominated for the FIFA Puskás Award at the 2015 FIFA Ballon d'Or. It finished as runner-up to a bicycle kick by Wendell Lira for Goianésia in the Brazilian third division.[30]

Barcelona had already won La Liga, and concluded their treble a week after securing the Copa, with victory over Juventus in the 2015 UEFA Champions League Final in Berlin. They became the first European club to win the national league, national cup and continental cup in one season on two separate occasions.[31] As Barcelona won both domestic tournaments, Athletic were the cup entrants in the 2015 Supercopa de España, in which they defeated Barcelona 5–1 on aggregate for their first trophy since their double in 1983–84.[32]
