MADRID, Sept. 2 (Xinhua) -- As expected, Thursday was a frantic last day to the transfer window in Spain, with plenty of deals going through before the market closed until January 1.
FC Barcelona were one of the busiest teams in the window, with striker Pierre-Emerick Aubameyang moving to Chelsea for around 12 million euros, while Martin Braithwaite rescinded his contract and immediately signed for Espanyol and Sergino Dest joined AC Milan on loan.
Hector Bellerin returns to the club he left as a teenager after terminating his contract with Arsenal, and Marcos Alonso will be allowed to join on Friday after rescinding his deal with Chelsea, allowing him to sign as a free agent.
Meanwhile, Memphis Depay is staying at the Camp Nou, despite rumors linking him to both England and Italy on the closing day of the market.
Real Sociedad announced the signing of Umar Sadiq from Almeria for an initial fee in the region of 20 million euros, plus variables. The tall, but skillful Nigerian will - along with Alexander Sorloth, who returned on loan 24 hours earlier - help cover for the departed Alexander Isak.
Ilaix Moriba returns on loan to Valencia from RB Leipzig, with the former FC Barcelona youngster going back to the club where he spent six months last season, and Justin Kluivert also moved to Valencia after failing to get a work permit to sign for Fulham.
However, Valencia's squad still looks weaker after Spain international Carlos Soler completed a move to Paris Saint-Germain, and forward Maxi Gomez joined Trabzonspor.
Villarreal replaced Pervis Estupinan, who joined Brighton last month, with Johan Mojica moving from Elche, with Elche signing central defender Federico Fernandez from Newcastle United.
Osasuna also made a last-day deal with winger Ez Abde agreeing a season's loan from Barcelona.
Girona signed 30-year-old goalkeeper Paulo Gazzaniga, who returns for a third spell in La Liga, while former Barcelona and Valencia midfielder Oriol Romeu also returns to La Liga to join Girona after seven years with Southampton.
One deal that didn't happen, however, involved Espanyol striker Raul de Tomas, who was set to join Rayo Vallecano, only for the two clubs to fail to complete the paperwork before the market closed. ■
