Tottenham's top four chances suffered a blow with their draw at Wigan Athletic.
Tottenham remain fifth with four matches to go, level on points with fourth-placed Chelsea and a point behind third-placed Arsenal.
Tomorrow's fixtures see Chelsea play Swansea at home and Arsenal host champions Manchester United.
And asked whether he regarded today's result as two points dropped or a point gained in the pursuit of Champions League football, Spurs boss Andre Villas-Boas said: "It depends on the results tomorrow of our opponents. It is intimately related to that.
"We can still be in control of our own destiny or not after tomorrow's results.
"Normally away from home a point is important at this stage of the season.
"When everybody needs three points, I think it is a difficult situation for teams.
"It all depends on what happens tomorrow."
