The midfielder will rack up his 100 appearance for us in all competitions if he features in the mouth-watering derby against Chelsea.
The Blues top the table while we have the best away record in the Premier League - it's all set up for a cracker at 5.30pm.
"I love to play against these teams - Chelsea, Arsenal - big London derbies," said Sandro.
"I feel happy when I play against strong players. I know some of their players very well (fellow Brazilians David Luiz, Oscar) and it's always a tough game, but always a happy day when you play them because you know it will be a brilliant game, a lot of goals, beautiful football, tackles and I like that!
"Chelsea are playing well and they are number one in the table. It's an important game. I can't wait!"
