Raul de Tomas is returning to Spain after just six months in Portugal in a 20 million euros ($22.2 million) move from Benfica to Espanyol, the two clubs announced on Thursday.
Espanyol issued a statement saying the Spanish youth international had signed a contract until June 2026.
De Tomas becomes the most expensive signing in Espanyol Barcelona's history, ahead of Argentina's Matias Vargas who arrived in July for 10.5 million euros. Espanyol are last in La Liga. The 25-year-old came through the youth system at Real Madrid, making one 14-minute appearance for the first team.
