In case you didnt see the game , the first two Leipzig goals were two headers Nkunku scored while being next to Ake. Not only did he beat Ake to the ball but Ake didnt even jump. Now imagine Lukaku instead of Nkunku.Did Ake play alone in defence?
You can check out the goals on youtube, you could argue that Ake had a fault in the 3rd goal as well.
