Will this prove to be the most entertaining La Liga campaign in recent years?
It certainly has that feel at the moment, with Atletico Madrid sandwiched in between the big two at the top of the table after 13 matches.
A three-horse race is developing, but who have been the five standout players in the league so far?
Thanks to WhoScored.com's statistics, we can tell you.
5. Diego Costa | Atletico Madrid | Rating: 7.75
Atletico Madrid fans had every reason to feel fearful after the departure of prolific striker Radamel Falcao in the summer. However, Diego Costa has filled the Colombia international's boots superbly this season, scoring 13 goals.
The 25-year-old, who recently opted to play for Spain over his native Brazil, earns a deserved WhoScored rating of 7.75 after an excellent start to the 2013/14 La Liga campaign.
4. Ivan Rakitic | Rating: 7.90
Arguably the most surprising member of this top five list is Sevilla midfielder Ivan Rakitic, who boasts an impressive 7.90 rating.
The 25-year-old has been the driving force behind a Sevilla side which has largely flattered to deceive so far this season, netting seven goals, including one against Barcelona and two against Real Madrid.
3. Neymar | Rating: 8.07
Barcelona's decision to spend almost £50m on Neymar was a gamble - but it's paying off dividends for the Catalan giants.
The 21-year-old has taken to life at Barca like a duck to water, scoring four goals and contributing seven assists in his first 11 matches for the club.
His 8.07 rating could go up even further in the absence of teammate Lionel Messi, who will be out until January with a hamstring injury.
2. Cristiano Ronaldo | Rating: 8.23
La Liga's top scorer, with 16 goals to his name already, Cristiano Ronaldo is currently in the form of his life.
The Real Madrid star has earned an 8.23 rating thanks to his phenomenal goalscoring exploits, although the fact Los Blancos are only third in the La Liga table may have prevented him from obtaining an even higher score...
1. Lionel Messi | Rating: 8.34
… which means that Barcelona's Lionel Messi occupies pole position, with a rating of 8.34.
The Argentina international has only - in comparison to his other-worldly standards, that's not that many - scored eight goals this season and was recently side-lined until January after tearing his hamstring.
With Messi, Barcelona won 12 of their opening 13 matches. Will they still be top of the table by the time he returns?
