Spurs have yet to win in two matches after drawing 1-1 with West Bromwich Albion at home on Saturday.
"He's cool," said Assou-Ekotto. "He has a different way to work, so we learn different things from him.
"He's like the son of [Jose] Mourinho because he used to work with him and he works in the same style. We do a little more tactics at training.
"If we work more about tactics we can win and we will enjoy [our football]."
Tottenham lost their opening game in the Premier League 2-1 at Newcastle United last weekend.
