The tackle was good - it wasn't a penalty. However from the camera angle you can see the referee had NO way of seeing Koscielny's touch of the ball. Unfortunately you've every right to feel aggrieved at this one. Not a penalty, but I see why it was given (incorrectly).
Disgraceful. Much like the Peno given against you. Not that I'm complaining. Benteke is in my fantasy team.
This Gareth grook dude is smoking something!! ""It is debatable penalty, it is 50/50. Why does Laurent Koscielny go to ground? Why does he not work and stay with the player? Wenger will tell them that. Stay on your feet and work the striker, make him do something special to beat you."
Because the referee went overboard in carding everyone, which means he has to card people for similar offences, which spirals into ridiculous calls such as the one against Koscielny.
