The 49-year-old, who was once assistant to Villas-Boas at Porto, has been out of football since leaving 1860 Munich following relegation to the German third tier in May. Pereira is tasked with breaking Guangzhou Evergrande's stranglehold on the Chinese Super League (CSL). Villas-Boas left SIPG two weeks ago after a turbulent season failed to yield a trophy despite reaching the last four of the Asian Champions League, the final of the Chinese FA Cup and coming second behind Guangzhou in the CSL.
