Liverpool defender Virgil van Dijk has played down his touchline argument with Jurgen Klopp.
The pair were involved in an animated spat after Napoli's first goal during Sunday's 3-0 defeat at Murrayfield.
But Netherlands international van Dijk insists such communication is necessary for success.
Van Dijk said: "Just things between me and him.
"It's not necessary to reveal what. I think everyone has to communicate with each other.
"Sometimes you have to tell someone the truth, that's how it is."
