Mikel Oyarzabal's transformation from Real Sociedad winger to Spain's central striker has been remarkable. The 29-year-old scored the Euro 2024 winner against England and has netted 13 goals in 16 caps since that Berlin final, leapfrogging Alfredo Di Stefano on the all-time list. Gaizka Mendieta believes he'll surprise people at the World Cup.

Fabian Ruiz has emerged as another unsung hero, winning back-to-back Champions League titles with Paris Saint-Germermain. Despite Rodri claiming Euro 2024's player of the tournament award, Mendieta argues Fabian outshone him. The midfielder's versatility allows him to operate anywhere from No 10 to defensive midfield, combining physical presence with surprising agility.

Spain's 31-match unbeaten run in competitive football shows their consistency under Luis de la Fuente. The midfield trio of Fabian, Rodri and Pedri provides tactical flexibility, while Lamine Yamal and Nico Williams offer pace on the flanks. Oyarzabal won't lack service with this creative lineup supporting him.

Injury concerns linger, though. Rodri struggled with Manchester City, Fabian is regaining fitness, Yamal faced an end-of-season scare, and Williams missed significant action. However, Spain's depth through Barcelona's Olmo, Gavi and Torres plus Arsenal's Zubimendi and Merino provides crucial backup options.
