Ralf Rangnick labelled Manchester United's defeat by Liverpool "embarrassing, disappointing and humiliating" after they were hammered 4-0 at Anfield on Tuesday.
Mohamed Salah netted a brace with Luis Diaz and Sadio Mane chiming in with goals to complete the route. Gary Neville and Roy Keane laid into Man United after the match, with the former calling the Red Devils a "waste of space" and the latter admitting he is more "sad" than angry these days.
Speaking after the game, Rangnick said: "It's embarrassing, it's completely disappointing and also humiliating, but we've got to accept that they're six years ahead of us. The team needs to be rebuilt - it's clear. I think a game like the one today showed that in a very drastic way that this rebuild is necessary."
