Well you can't say Barcelona are the more dedicated team in the Laliga cause their rivals Realmadrid is also have dedicated players that are performing well this season and currently at the top of the table and unlike the previous season, Madrid are very serious and are try to maintain their position in the table to enable them achieve the league trophy, Barcelona have Madrid to contest with and I believe this season's would be more interesting than the previous, cause they both signed quality players that's been helping them to be successful this season.
However Barcelona's performance this season is very brilliant as expected cause they're the title defenders and of a truth they've got players that are very hardworking and I believe that's why they're the only team that are currently unbeaten in the league.
Hopefully Barcelona will have better luck than Real Madrid when they meet Atletico, but the match is still very long away and if there are no schedule changes it will happen in week 15. Madrid and Barcelona are competing closely on the standings with a difference of 1 point, Madrid lost 3 points because they suffered one defeat, Barcelona lost 4 points because they drew two matches. The fight for the La Liga trophy this season is indeed tighter, I think when the season ends the difference in points will not be as big as last season.
However, it is still very early to talk about the end of the season and winning trophies, so both of them must focus on securing points in every match. The tight competition schedule and the storm of player injuries are always a challenge, for both Madrid and Barcelona, Girona and Atletico could steal the opportunity if Madrid and Barcelona experience a decline in performance.
