Tottenham boss Andre Villas-Boas concedes they're out of the title race.
Spurs host Liverpool today at White Hart Lane.
AVB said: "It's difficult. Arsenal have taken this margin (lead) which is important. The margin could easily change but they are doing extremely well. I would suppose they would be able to hold on."
He added: "It's a big, big challenge because Liverpool sit in front of us and we don't want that margin to grow any bigger," he continued. "It will be difficult, but we will be level on points with them if we win and it would put us in a very, very good position."
