I'm with you.
I'm surprised to see so little mention of the penalty that wasn't. The replays clearly showed Lamela's clip was outside the box. Not a penalty.
Also, in the fist phase of the move, Coutinho (I think) was offside, yet our defender reacted to his run so the attacker has to be active, surely? The ball was over hit and ended up with Firmino, who then went on to get the pen.
Also, there was the Matip foul on Janssen where we could easily have got a pen, and the free kick we got right on the edge - I'd like to see if that foul was on the line.
We weren't brilliant, but if anything they were luckier than us, especially with decisions.
