Liverpool manager Jurgen Klopp says he regrets the headlines created by his comments about referee Paul Tierney after Sunday's 4-3 win over Tottenham.
Klopp said Tierney appears to have something "against" his team after he was shown a yellow card for celebrating in front of the fourth official.
Referees' body the Professional Game Match Officials Limited (PGMOL) refuted Klopp's claims.
"The whole situation should not have happened at all," said Klopp.
"It was out of emotion and anger in that moment. That's why I celebrated the way I did.
"We won a game 4-3 in a spectacular manner and the only headlines I created and I really regret that.
