Newly-crowned Spanish champions Real Madrid and runners-up Barcelona have killed the proverbial fatted calf this summer in an attempt to establish preeminence in La Liga next season.
Valencia have not been far behind as they also seek to challenge the top two, who have spent more than 100 million euros (130m dollars) between them.
Real have captured German international defender Christoph Metzelder from Dortmund and Pepe from Porto while landing Javier Saviola - on a free transfer - from Barca, as well as taking Spanish international forward Roberto Soldado back from his loan at Osasuna.
New coach Bernd Schuster hasn't finished there as Real also try to secure a transfer for Jose Antonio Reyes, who was on loan last season from Arsenal, as well as pluck winger Arjen Robben from Chelsea.

Barca, beaten to the wire in the title race, have landed four players to date after agreeing to sign Argentine international Gabriel Milito from Zaragoza for a reported 20 million euros, ten million less than Real paid for Pepe.
Barca had earlier splashed 24 million euros on Thierry Henry, having chased the former Arsenal man for more than a year, though it remains to be seen if he can fit into a forward line already comprising Samuel Eto'o, Lionel Messi and Ronaldinho.

Barca sporting director Txiki Begiristain explained: "We have fulfilled our objective of strengthening the team and now we have to work on who is leaving so we can end up with the desired squad on August 31 (season starts)."
French midfielder Ludovic Giuly, who won the Champions League with Barca in 2006, has agreed to join AS Roma for an initial 3.2 million euros, rather than the six million the Catalan club hoped for, though another 1.2 million could come if he helps the club qualify for the Champions League.
