Liverpool cruised by Burnley in a 3-0 win at Turf Moor, with Alexander-Arnold appearing to open the scoring when his over-hit cross dropped behind Nick Pope’s head and into the goal.
Despite being an assist machine, Alexander-Arnold has only ever scored two goals in the Premier League.
The fluke goal set Liverpool on their way to a convincing victory, but Klopp was left shocked when he was told after the game Alexander-Arnold would not be credited with the goal.
He replied, stunned: ‘Really? How is that possible?’
‘Well okay, we’ll make do anyway,’ he continued after being told of the deflection off Chris Wood.
‘Err, well yeah. Okay we were a bit lucky with the own goal but anyway we forced that situation.’
Liverpool set a new club record with their victory over Burnley, registering their 13th straight win.
‘I didn’t know before the game that we had 12 straight wins but now it’s 13, Klopp said.
‘Newcastle are waiting on the other side of two international games for most of the boys.
‘We want to have them all healthy back for what will be an unbelievably intense run of five away games and one home game.
‘We have a lot to travel and a lot of things to do, but if we play like today with the same attitude, we have a good chance to win more games.’
The result sent Liverpool back to the top of the league table, with international fixtures now putting club football on hold for two weeks.
