Erik Lamela is frustrated at being Tottenham's only injured player and has returned to former club AS Roma to undergo treatment, according to manager Mauricio Pochettino.
Lamela is struggling to shake off a troublesome hip problem and has not played for Spurs since their 2-1 EFL Cup defeat to Liverpool on October 25.
The 24-year-old's recovery was then delayed in December by a family issue, which meant he spent one week in Argentina visiting his brother in hospital.
Lamela has since returned to London but has played no part in Tottenham's recent resurgence, including five Premier League wins in a row and Wednesday's superb 2-0 victory over Chelsea.
