Both Wayne Arendse and Rodgers have left the relegated People's Team to join the Brazilians for the new season.
Tyren Arendse says the duo will have to learn to handle pressure from supporters.
"There are a lot of expectations from the club and the Sundowns fans as well. As a player you know that the most important thing for them is to make sure that they are physically and mentally strong," Arendse says.
"Sundowns have a lot of quality players, but with their ability I know both Wayne and Eleazar will able to fight for their positions.
"I think they knew what they wanted and this is an opportunity for them to further their career, and it's important that you experience things for yourself."
Tyren Arendse says he did not talk to Wayne Arendse before he left Cape Town, but did get the chance to speak to Rodgers.
"I didn't speak to Wayne before he left, because everything happened so fast, but Rodger came to me and asked for advice and of course I gave him a few pointers and things he should expect.
"Both players are well equipped to play regularly; Sundowns wouldn't want them if they didn't think that they are quality players.
"If a team like Sundowns ask 'sign here', you shouldn't doubt your ability. The most important thing is to go out there and enjoy yourself because that's what football is all about."
Tyren Arendse spent a few years at both Sundowns and Pirates before rejoining Santos in the 2008/09 season.
