Tottenham boss Harry Redknapp says Arsenal's title hopes ended in their defeat to Chelsea.
With a third of the season gone, Spurs are only behind Chelsea and Manchester United, with Redknapp viewing the title as being a two-horse race.
Arsenal's challenge faltered against Chelsea, and Redknapp insisted: "I don't think we learned anything from the weekend. I said weeks ago I could see Chelsea and Man United fighting for the championship.
"I can't see Arsenal winning the championship, you saw just how strong Chelsea are, they've got everything, and you can never write United off. I spoke to Alex two weeks ago and he said he felt the same way.
"For us to get into the Champions League would be a real big achievement. Everton did it the other year. Why not? Of course it could happen, Villa and Man City could (also) get in there this year.
"There's an opportunity but it will be very hard. We have a good a chance as anybody."
