If you actually look at the goals we have conceded against them of late, most can be attributed to basic defensive errors or shots from outside the penalty area.
For the 4-3, Delph gives up cheap ball and a shot along the ground beats Ederson.
Gundogan gives Otamendi a hospital back pass and then Mane is in.
Stones needs to be stronger but gets pushed far too easily for another.
Ederson then goes walkabout and ball is returned from 40 yards.
In the Champions League tie, Sane gives the ball away with a stupid ball across the midfield and Walker fails twice to clear the ball and Ederson is weak as fuck with a push out back onto play before Salah accepts the incompetence.
Then it's a screamer from Chamberlain after Gundogan fails to clear and wanks out of a challenge.
At our place, tiredness plays a bit part but Otamendi gets done easily and then Firmino is shown a clear route to goal.
All of the above was easily preventable, nowhere are we being undone.
It is basic pressed errors in possession. The margins are very fine, Otamendi hits the crossbar with a header at 1-1, we are a whistle away from two legitimate goals being allowed and the thud of a post from Bernardo.
