Tottenham's Erik Lamela scores their second goal
Lamela has had operations on both hips in Barcelona in the past three months, and has started his rehabilitation in Argentina. He is not expected to return to the training ground before October, which means he will be sidelined for a year.
The 25-year-old made his last appearance for the Spurs in the 2-1 EFL Cup fourth-round defeat to Liverpool, in October last year.
The Times reports that Lamela spent much of January working with Damiano Stefanini, the physiotherapist at Roma, his former club.
His extended absence led to wild speculation on his future and especially on his relationship with Mauricio Pochettino, but the Spurs manager has ruled out selling him.

Left-back Danny Rose is also expected to miss the start of 2017/18 season. The England left back, who has been targeted by Manchester City, is likely to return in August.
Rose had an operation last month on a knee injury sustained in January.
Another player who could miss the start of next season is Son Heung-Min, who will undergo a surgery on his fractured right arm sustained during South Korea’s 3-2 defeat against Qatar earlier this month.
