Jurgen Klopp played down the on-field argument between James Milner and Virgil van Dijk after Liverpool lost 2-1 at Manchester United on Monday night.
The Reds fell behind for the seventh successive Premier League game when Jadon Sancho rolled the ball home after flooring Milner with a dummy inside the area.
Marcus Rashford doubled the advantage in the second period before Mohamed Salah's header reduced the deficit inside the final 10 minutes - but United held on for three points.
