The iconic ‘Tamudazo’Several decades after that 1949 meeting, RCD Espanyol gained some revenge as they denied FC Barcelona the 2006/07 LaLiga Santander title with a dramatic 2-2 draw at the Camp Nou. RCD Espanyol legend and captain Raúl Tamudo stepped up in the dying minutes of their encounter on the penultimate day of the season to score a brace and cost FC Barcelona two crucial points. The five points Barça dropped against RCD Espanyol that season – Frank Rijkaard’s side lost 3-1 in the reverse fixture earlier that season – cost them dearly as they went on to lose the LaLiga Santander title to Real Madrid.With Busquets gone, iconic Barca team is officially in history books4. RCD Espanyol hold the record for the biggest Barcelona Derby win in historyFC Barcelona may have the better head-to-head record in this fixture in the more than 90 years since it was first played in LaLiga but it was actually RCD Espanyol who recorded the biggest ever Barcelona Derby win: a whopping 6-0 victory in April 1951.5. Ernesto Valverde played for and coached both clubsHe may have recently been FC Barcelona coach, but Ernesto Valverde had a particularly productive spell in charge at RCD Espanyol too, between 2006 and 2008. He led the team to the 2007 UEFA Cup final, where they dramatically lost on penalties to Sevilla FC. As a player, he also played on both sides of the divide: at RCD Espanyol from 1986 to 1988 and at FC Barcelona from 1988 to 1990. Despite being one of the latest FC Barcelona coaches, between 2017 and 2020, Valverde’s connection with RCD Espanyol is so strong that Gate 89 at the RCDE Stadium still carries his name to this day.
