Liverpool striker Alexander Isak faces a lengthy spell on the sidelines after the Premier League champions revealed he had surgery on an ankle injury that includes a fibula fracture on Monday.
Isak, signed from Newcastle for a British record 125 million 168 million in September, suffered the injury in the process of scoring in Liverpools 2-1 win at Tottenham on Saturday.
The 26-year-old was tackled by Tottenham defender Micky van de Ven and limped off immediately after his goal.
