Villarreal have exceeded expectations upon their return to La Liga.
Just one year after spending a season in the Spanish second division, Marcelino's side have shot up the table, where they currently occupy the 50th spot.
What they lacked in attack against Barcelona, they made up for in defence. Goalkeeper Sergio Asenjo and centre-back Mateo Musacchio turned in excellent displays.
Villarreal's back four of Mario, Musacchio, Chechu Dorado and Jaume Costa proved difficult to break down, and Neymar's penalty was the only difference between the sides in the first half.
As reported on WhoScored.com, Barcelona enjoyed 76 percent of possession throughout the game and had 13 shots on goal (seven on target). Were it not for the impressive efforts of Asenjo in goal, the damage would have been a lot worse.
Villarreal have the third-best defensive record in La Liga and will continue to needle the league's top teams. After taking points from both Madrid and Atletico Madrid, they cannot be underestimated, despite coming away from Camp Nou with nothing.
