Sandro will join the squad again in training next week.
"It's a very good start to pre-season for both players," AVB told the Spurs website.
"It's great for Younes after a year out to come back to training and have double sessions with no problems.
"Sandro hit six months last week (he was injured on January 12) and we are on plan, he's made an excellent recovery and we're very happy with him.
"One more week and he'll join the group and he will also join us for full training in Hong Kong."
