Rio Ferdinand says Manchester United have some “big decisions” with the regards to the future of manager Jose Mourinho following the defeat to West Ham on Saturday.

The Red Devils slumped to a 3-1 defeat at the hands of the Hammers, with goals from Marko Arnautovic, Felipe Anderson and an own-goal from Victor Lindelof sealing an afternoon to forget for Mourinho’s side.

The defeat is their third in the top flight this season already, meaning this is their worst start to a top-flight season since 1989-90.

United were also knocked out of the Carabao Cup by Championship side Derby County earlier this week, and Ferdinand has now hinted it could be time to part ways with the Portuguese boss following their dismal run of form.

“There will be conversations at the top level about the future of the manager and the squad,” Ferdinand told BT.

“The basics are not being done and something has to be said.”

He added: added: “You can’t let a situation like this continue throughout the season – wars in the press, leaks, players on one side of the dressing room, Mourinho and his staff on the other.

“If that continues this will be one of the worst seasons in the club’s history.”
