Mikel Oyarzabal (20), Real Sociedad
The winger has come through the ranks at Sociedad and broke into the first team last season. He has been ever-present since then bar an injury causing him to miss three games in September. Oyarzabal returned, however, with a goal and an assist in his side's 3-2 defeat to Valencia last weekend.
Carlos Soler (20), Valencia
Soler, tipped to become a future Valencia captain and Spain star, has helped Valencia regain their form under Marcelino. So far this season, he has provided more assists from open play than any other player in La Liga.
Nacho Vidal (22), Valencia
The full-back was handed a new contract by Valencia amid interest from a number of other teams, and he has rewarded the club with strong performances on the pitch. Vidal is currently fighting for the right-back position with Martin Montoya, but the youngster clearly has a bright future ahead of him.
Enes Unal (20), Villarreal
Villarreal may not have enjoyed the strongest start in La Liga this season, but they certainly claimed a real coup in signing the striker from Manchester City this summer. Unal joined the Spanish outfit for £12m, but only on the basis that City can re-sign him for £17.5. He scored an absolute screamer against Real Betis, and if he continues that kind of form, he will probably end up back in the Premier League.
Enis Bardhi (22), Levante
This could be one of the signings of the summer. Levante paid a mere €1.5m for the Macedonian's services and he has already scored three goals in six games for the club, making him the highest scoring midfielder in La Liga.
