Surely we can't blame Ake's run entirely on Trent...
Yes he could have done better, but it happens to the best of them. Everyone will lose a challenge or two now and then especially in an area as vast as the midfield. Our own Matip regularly glides through opposition midfields, a midfield consisting of City's Rodri included.
That goal was a team mistake. Half the team could have done better to prevent it. That is all there is to it.
Moreover, the person at fault for that goal was Alisson - it was his fault, pure and simple.
