Barcelona: Espanyol won 1-0 at 10-man Granada thanks to Manuel Lanzarote's 76th-minute free kick on Sunday, keeping the Barcelona-based side unbeaten through four rounds of the Spanish league.
Lanzarote gently curled the ball off the post and into the net from a free kick inside Granada's area awarded to Espanyol after the referee ruled that goalkeeper Roberto Fernandez had handled a back pass from a defender.
Televised replays showed that the ball appeared to take a deflection off an Espanyol player, suggesting that the free kick should not have been given.
Granada's tempers boiled over in the 82nd when substitute Odion Ighalo received back-to-back bookings, both for protesting to the referee.
Elsewhere, Getafe striker Nicolas "Miku" Ladislao netted a double in a 2-1 win over last-place Osasuna, ruining the debut of new coach Javi Gracia.
Osasuna started brightly on the road in Madrid with Roberto Torres opening in the 24th, but Miku headed in a corner kick that sailed over goalkeeper Andres Fernandez to level in the 35th.
After his acrobatic kick had sent the ball off the woodwork, Miku used a nifty back-heeled touch to slip the ball around a defender before placing his second goal just inside the post in the 52nd, sending Getafe on its way to its first win of the season.
Osasuna almost grabbed the draw when Oriol Riera hit the crossbar in the 85th, but it remained the only team yet to take a point in Spain's topflight.
Later, Real Betis hosts Valencia before both turn to the Europa League later this week, and Malaga welcomes Rayo Vallecano.
