Liverpool manager Jurgen Klopp insisted “the whole thing should never have happened” as he explained his part in the row which has blown up between him and referee Paul Tierney. The Football Association is investigating comments by the Reds boss which appeared to call into question the integrity of the official following Sunday’s dramatic 4-3 win over Tottenham. After his side’s late winner, Klopp ran down the touchline to celebrate in front of fourth official John Brooks and received a yellow card from Tierney. “The whole situation shouldn’t have happened at all. It was out of emotion, out of anger in that moment. That’s why I celebrated the way I celebrated,” Klopp said.
