"A couple of days ago, we were exactly the opposite," Villas-Boas is quoted as saying by ESPN. "This is a very special night for us but our quest is to qualify for the Champions League.
"It is very difficult to go for the title. We understand it is a place where the great teams of this country belong.
"We want to win a trophy this season - and we want Champions League qualification."
Villas-Boas was appointed the Tottenham manager at the start of the season.
