Lamela is convinced he retains the confidence of the Spurs boss and is sure he will get enough game time for him to be considered for next year's World Cup.
"My moment will come and I will make the difference," Lamela told the London Evening Standard.
"You always train thinking that you're going to play. Sooner or later, my moment will arrive and I have to be ready. That is the way I am looking at it.
"I get on very well with Andre Villas-Boas. He is a great guy who clearly thinks about the future. Because of this, coming to Tottenham is a great step for me and in the future, we'll see why.
"Of course, it's also important for me to get into the Argentina squad for the World Cup, but I'm confident I'll play here. We are involved in four competitions so there are many games ahead."
