"No, I am not sure exactly, we played on quite a while, but lost concentration, no," Klopp said in his post-match press conference.
"It was a massive warning sign obviously. When the ball is in the air, you have to avoid two things – the first thing is, the ball going into the box and that's only possible when you are there where they shoot the ball into the box.
"For that you should not stand too deep, which we were in a couple of moments because in the box a lot of things can happen. We cannot defend like they can attack; they can take the risk, we can't because of penalties and all these kind of things.
"We lose this little challenge and then he [Willock] is free in front of Ali and then deflected on top of that. I don't think it was a concentration thing, but it was bad enough to give them the chance to score."
Liverpool were given a massive chance to win the game when Callum Wilson's goal was disallowed by VAR but conceded nonetheless within the next few minutes.
While the defenders can all take a look at their involvement in the goal, the game really should have been put to bed by the forwards much earlier than that.
