Spurs' hopes of producing a top-four finish in order to qualify for the Champions League took a slight hit as they now sit a point behind fourth-placed Arsenal and three in arrears of the third-placed Blues with two fixtures remaining.
But Villas-Boas knows how erratic the Premier League can be and was holding hope that the right results would allow Tottenham to sneak into a Champions League position.
"We wanted to win obviously," he told Sky Sports 1.
"The feeling is that a point is not bad, but it is not dependent on us now. Someone will have to drop points. The task was to win here.
"Anything can happen. The Premier League is completely unpredictable. Chelsea have a difficult game against (Aston) Villa at the weekend.
"We have a difficult game against Stoke as well who are also fighting.
"This fixture before the emotions of the last day can be decisive."
