The Brazilians take on Esperance away in Rades on Wednesday night.
Sundowns will need to get at least a draw to be in a good position to progress to the quarterfinals of the Champions League.
You can also enjoy photographs of the team training just before their trip to Tunisia.
There's also a wonderful photo of Downs star Percy Tau meeting up with Al Ahly player Ahmed Fathi on the way to North Africa.
