Jurgen Klopp appeared relaxed after James Milner laid into Virgil van Dijk after Liverpool conceded the opener at Manchester United.
Jadon Sancho set the hosts on their way as they recorded their first win of the season at Old Trafford. Marcus Rashford doubled United's lead in the second half and the Red Devils held on after Mohamed Salah's late goal gave Liverpool a glimmer of hope.
It was after Sancho's opener that Liverpool midfielder Milner, who is known as one of the team's leaders, lamented the Dutch centre-half as the visitors were continuously cut apart. Rashford got in behind initially and a neat one-two saw United again scythe through the visitors' backline.
