Liverpool manager Jurgen Klopp revealed on Friday that Arthur had sat out the midweek Champions League victory over Rangers due to the injury and after further assessment, the medical staff at the Merseyside club have decided that an operation is the best way forward in treating the problem, reports The Athletic.
The 26-year-old won’t play again for the Reds until 2023, which is a huge setback for the Brazilian.
Arthur joined Liverpool on loan from Juventus on deadline day as the Reds looked for help in dealing with their lack of bodies in midfield but has not played much due to fitness issues.
The Brazilian has clocked up just 13 minutes for Klopp’s side so far this campaign and worked over the international break in order to get fit for when the season resumed.
After all that effort, this is an unfortunate thing to happen to the midfielder as his chances of getting game time now for Liverpool seem very slim as all their midfielders are likely to be back when the 26-year-old recovers.
