Thierry Henry believes Tottenham have turned this season's Premier League title battle into a four-horse race.
The Sky Sports pundit was speaking after watching Arsenal slip to third in the table following a 1-0 home defeat to Chelsea with Spurs lurking just two points behind their North London rivals with 15 matches to play.
Leicester's 3-0 win over Stoke saw them go three points clear of second-placed Manchester City who could only manage a 2-2 draw with West Ham this weekend.
And Arsenal legend Henry has been forced to admit that Spurs are realistic contenders along with the rest of the top four following their 3-1 win at Crystal Palace.
He told Super Sunday: "Now, Tottenham, coming from nowhere, are two points behind Arsenal and nobody has been talking so much about them winning the title. Now, they are well in it. It's a four-team race for the title.
"They are in it. They are two points away from Man City and Arsenal with +22 goal difference. Arsenal have to go to the Lane. I never thought I would have said it, but they are in it."
Arsenal's title hopes were dented by last season's champions Chelsea, who claimed a 1-0 win after Per Mertesacker was sent off for the home side on 20 minutes.
Arsenal have not beaten Chelsea in a league game in their last nine attempts - and Henry feels the result will have a psychological impact on the players.
"It's always the same thing," he added. "There's always a big expectation when Arsenal play Chelsea. Can they finally beat them? And again it's Diego Costa and Chelsea having the last laugh.
"It's difficult to point to things after the sending off because it's always going to be difficult, but they didn't start the game well enough to be able to get on top.
"Is this defeat going to have a massive impact on the title race? Yes, it is in a way because you still didn't beat Chelsea but on the other side no-one is really capitalising or taking advantage of mistakes from other teams."
