Tottenham boss Andre Villas-Boas insists their top four hopes are not assured.

Spurs moved back above Chelsea up into third place in the Barclays Premier League after victory over Arsenal.

"At the moment we keep our feet on ground. We still have some difficult games to play against big teams - Liverpool, Chelsea and Manchester City plus Everton - teams who have same objectives as ours, so it hasn't finished yet. Everything is still possible and we just have to gather the most amount of points that we can.

"There is a great focus on trying to make this year the year we qualify for the Champions League once again. Everybody is bonding together regarding our objective.

"The players are our main reference as they have been absolutely outstanding. They make it public - they want to be in it. Their desire has been tremendous in these recent games."
