A hefty price tag and a four-month ban mean Luis Suarez just misses out on the top five, but once he's back he could be the difference between Barca winning or losing La Liga.
Cartabia and Vico (Cordoba)
Two young players going by the name of Fede are both on loan at Albert Ferrer's Cordoba this season and both have bags of attacking talent. Fede Cartabia has arrived from Valencia and has already scored, while Fede Vico has returned from Anderlecht.
Espanyol lost David Lopez to Napoli but did well to replace him with Jose Canas. It didn't work out for the midfielder with Swansea, but if he recaptures his Real Betis form, Los Pericos will be delighted.
Nordin Amrabat excelled on loan at Malaga last season; without him they may have finished much lower than 11th. To bring him back this summer was a clever move.
Navas and James (Real Madrid)
If Keylor Navas displaces Iker Casillas he could go on to be Real Madrid's first choice for the next five seasons. As for James Rodriguez, he too has all the tools to create a legacy for himself in the Spanish capital.
Vidal and Banega (Sevilla)
Sevilla snapped up Aleix Vidal from Almeria and Ever Banega from Valencia. The latter, in particular, could become a star...it's just about coaxing it out of him and keeping him motivated.
Suarez and Deulofeu (Sevilla)
Both Denis Suarez and Gerard Deulofeu arrived in Andalusia from Barcelona this summer and both have the potential to rank among the best players in the league. Sevilla will be happy if just one hits that mark.
Victor Ruiz (Villarreal)
It never quite worked out for Victor Ruiz at Valencia, but already, after just two games, he's looking like being a top defender for Villarreal.
