Rivaldo and Casemiro were teammates when they were playing for Sao Paolo.
Rivaldo was 41 when he finally retired from playing at Mogi Mirim in 2015 – the club he left to join Sao Paulo in January 2011.
He was 38 and heading into the twilight of his career, but it didn't stop him from scoring a lovely goal on debut against Linense – one of his five in 30 games that season, as Sao Paulo finished sixth and reached the knockout stage of the Copa Sudamericana.
Casemiro was only in his second season as a professional when the Brazilian legend rocked up at the Estadio do Morumbi, and was just shy of his 19th birthday.
The future Real Madrid man was a regular at the heart of midfield, however, leading to his 2012 transfer to the Spanish giants.
