Tottenham boss Andre Villas-Boas was delighted with their 1-0 win over Southampton.
"We are still in a great position but it will be extremely difficult," said Villas-Boas, whose former employers face Manchester United today.
"We have a great week ahead of us with two away games, that are decisive to keep us in the frame.
"Everything is in our hands and we hope to make that final push. The game against Chelsea will be a massive, massive game for us.
