Robbie Keane has joined Indian Super League champions Atletico de Kolkata, who are managed by his former Tottenham team-mate Teddy Sheringham.

Keane, the Republic of Ireland's record goalscorer, has been searching for a club leaving LA Galaxy last November.

The 37-year-old's 10-club career has included spells at Leeds, Liverpool and Celtic.

"The offer to experience a new league and culture in Asia appealed to me," said Keane, who won 146 Irish caps.
