Luis Garcia scored two goals - including the injury-time winner- as Zaragoza beat Espanyol 2-1 on Sunday in the Spanish league.
The Spanish forward, who joined Zaragoza earlier this month after six years with the Barcelona-based Espanyol, headed Zaragoza's first goal of the season in the 29th.
Defender Javi Lopez equalized for the visitors in the 71st, and Espanyol looked set to earn an away draw when goalkeeper Cristian Alvarez blocked Garcia's penalty kick in the 87th.
But the 30-year-old Garcia appeared in the area to volley in a loose ball three minutes into injury time to earn Zaragoza's first win of the season.
Earlier, Michu scored early to give promoted side Rayo Vallecano a 1-0 win over Getafe - its first victory in Spain's top flight after eight seasons in the lower division.
Michu was well placed at the far post to head home a corner kick flicked on by Botelho in the fourth minute.
Getafe was limited to a tame volley by Pedro Leon on his return on loan from Real Madrid and a shot by Dani Guiza that Rayo goalkeeper Daniel Gimenez did well to block either side of halftime.
Rayo then held on against winless Getafe to claim the Spanish capital derby.
''Finally we took the three points,'' said veteran Rayo midfielder Jose Movilla. ''The way we played in the previous two games against Athletic Bilbao and Zaragoza, we could have nine points by now.''
Later Sunday, Madrid aims to extend its perfect start to the season at Levante. Real Betis also looks to stay perfect at Athletic Bilbao, and Atletico Madrid hosts Racing Santander.
