Spurs yesterday confirmed that their former skipper, who had two spells at White Hart Lane, was to spend a fortnight training with them before returning to LA for the start of the Major League Soccer season in March.
The Ireland skipper enjoyed a successful stint at Aston Villa during last season's American winter break and had been linked with a similar move to QPR, while Spurs have a vacancy up front as Emmanuel Adebayor participates for Togo in the Africa Cup of Nations.
With Ireland's key qualifiers against Sweden and Poland taking place just two weeks into the MLS season, Ireland manager Giovanni Trapattoni will hope that a period working at Tottenham will help Keane to hit the ground running in the spring.
Meanwhile, Richard Dunne and Marc Wilson will return to training this week, giving Trapattoni a boost ahead of the upcoming friendly against Poland and the vital World Cup games.
The duo are unlikely to be available for the February 6 meeting with the Poles at Lansdowne Road, but Wilson believes he will be back for the Sweden game on March 22 in Stockholm.
"If everything goes according to plan I'll be back and fully fit well before the Sweden game," he said. "I have had a few texts from the Ireland manager, asking how I was getting on, so I was able to tell him that things are on course."
