The Liverpool forward Luis Díaz has been ruled out until December with a knee injury sustained in the 3-2 defeat against Arsenal on Sunday. Scans have revealed the Colombia international does not require surgery, but the injury will keep him out until after the World Cup. It means the 25-year-old, who left the Emirates Stadium on crutches with his knee in a brace, will miss at least 10 matches for Jürgen Klopp’s struggling side. Díaz will miss a number of key games, including the visit of Manchester City on Sunday and a trip to Tottenham the following month, as well as Champions League matches against Rangers, Ajax and Napoli. Díaz will not miss out on the World Cup given Colombia did not qualify for the tournament in Qatar. Trent Alexander-Arnold also injured his ankle against Arsenal, leading to him being replaced by Joe Gomez at half-time, but Liverpool are still awaiting an update on the damage.
