Spurs dropped to eighth, two points behind their rivals and one behind seventh-placed West Ham -- who host Stoke on Monday.
Swansea claimed 10th place with a 2-1 win over Newcastle, who went into the match threatening legal action against Senegal's national federation after Papiss Cisse was refused permission to play.
The striker did not travel to Niger for a midweek friendly due to a back injury, so Senegal invoked FIFA's five-day rule that stops players from missing internationals and returning immediately to play for their clubs.
"I love playing for my country and would only withdraw from a squad -- for either a friendly or competitive game -- for a genuine reason," Cisse said.
"I am fully supportive of the position my club has adopted in this matter and am sorry that the Federation seem to doubt my honesty and integrity. I will now consider if I wish to continue to captain my country."
Spanish striker Michu and Canadian Jonathan de Guzman put Swansea ahead before a late consolation from Cisse's compatriot Demba Ba -- the forward's eighth league goal this season.
Liverpool moved up to 11th with a 3-0 win over Wigan as Luis Suarez continued his goalscoring run -- and again ran into controversy.
The Uruguay striker netted a double to move to the top of the EPL charts with 10, but was accused by Wigan manager Roberto Martinez of stamping on David Jones.
"The first finish is probably the real clinical one and a sign of a top player," Martinez said.
"He was very fortunate because it was a stamp which the referee didn't see, and that wasn't the sign of a top player."
Queens Park Rangers lost 3-1 at home to second-bottom Southampton, leaving Mark Hughes' team four points adrift at the foot of the table as the Welshman battles to save his job.
