68 games - so long was the loss-free suite at Anfield for Liverpool in Premier League football.
Tonight, the reigning champions were defeated at home - for the first time since April 23, 2017 when Crystal Palace won 2-1.
Liverpool had chances to break the deadlock, including Divock Origi scoring the crossbar at the end of the first half.
But it did not work out for Liverpool this evening either.
Jürgen Klopp's team, which before the round had to settle for one point in three of the last five league matches, looked to be heading for a draw again.
However, the defense were on their toes and allowed no space for a finish. 83 minutes into the match, the referee signaled for a Ashley Barnes substitution.
Barnes took care of the penalty himself and made no mistake.
Liverpool then pressed for a draw, but it never came.
Liverpool, who in fact have not even scored a goal in the league in 2021, slip with the loss down to fourth place in the limping Premier League table.
The distance up to league-leading Manchester United is now six points.
Burnley, on the other hand, lifts a position, from 17th to 16th.
