Luíz, 29, played for Fluminense FC and Santa Cruz FC in Brazil before leaving for Portugal in 2001. He spent a year with Varzim SC then joined Braga, for whom he made 69 Liga appearances over two and a half seasons. Frechaut, 28, returns to Portugal after 12 months in the Russian capital. He played 15 Premier-Liga games for Dinamo after arriving from Boavista FC on a three-year contract last January.
Both sides have also made further additions to their squad, with Dinamo adding more defensive steel by recruiting 22-year-old Argentinian centre-back Leandro Fernández from CA River Plate. Meanwhile, Braga have signed Brazilian striker Matheus on a three-and-a-half year contract after the 23-year-old departed Portuguese second division side FC Marco.
