Real Betis with some interesting, if perhaps risky, signings this season. Van der Vaart, Portillo from Málaga, Pezzella from River, Didier Digard of OGC Nice, Westermann from HSV and Juan Manuel Vargas of Fiorentina.
Some other more low-key, yet interesting transfers in Spain so far,
Moi Gómez, Vergini and Víctor Rodríguez to Getafe (all on loan though)
Andrés Fernández and the fearsomely nicknamed Nico "el Conejo" López (if you see his mug, you'll get it
) to Granada
Fede Cartabia (loan) and Cani to Depor
Jonathas to La Real
Ebert to Rayo
Borja Bastón to Eibar (canterano from Atléti who scored 23 goals on loan to Zaragoza in Segunda last season)
Sergio Araujo to Las Palmas (they had him on loan last season and have now bought him; also scored 23 goals in Segunda)
Toni Sanabria (loan) to Sporting
