Barcelona: Roque Santa Cruz scored twice to lead 10-man Real Betis to a thrilling 4-3 win over Zaragoza on Thursday as the newly-promoted Andalusian side moved top of the Spanish league standings.
Goals from Santa Cruz and Salva Sevilla - from the penalty spot - after just 12 minutes set Betis on their way to match the best-ever start of a promoted club with four straight victories.
Former Celtic defender Efrain Juarez pulled one back for Zaragoza before half-time, but Benat Etxebarria stroked home another penalty in the 47th and Santa Cruz headed in his second goal two minutes later.
