Keane training at Spurs pending possible loan
Keane, 31, who will lead Ireland in the Euro 2012 finals in Ukraine and Poland, is planning to train with Spurs during January to maintain his fitness during the MLS close-season.
Spurs confirmed the arrangement on their website on Monday but he could find himself playing for Aston Villa if the reported interest from manager Alex McLeish comes to fruition.
McLeish came close to signing Keane last year when he was manager of Birmingham City and Keane was still at Spurs.
Keane's temporary move back to England continues a trend with his Galaxy team-mate Landon Donovan spending two months on loan at Everton and New York Red Bulls striker Thierry Henry about to re-join his former club Arsenal on loan for two months.
David Beckham, another LA Galaxy player, has also trained at Arsenal and Spurs during the MLS break over the last two years.
