Not only are you playing pathetically it seems that the attitude of your players & manager is now that you are nothing more than a mid-table club and that you have zero ambition.
To quote Jordan Henderson after your pathetic display tonight:
"We knew it would be a tough game, they are a very good team technically but we showed great character to stay in the game, we looked dangerous on the counter and were more solid tonight but disappointed to concede late on."
You were playing a Bulgarian side who had never before made it to the group stage of the Champions League and whose best ever performance to date was the last 16 of the Europa League and who have a squad full of nobodies and Henderson is making excuses? They're not a "very good team technically", they're arguably one of the worst two or three sides in the Champions League this year. Resorting to having to play counter attacking football against a team like that in order to stand any chance of getting something from the game is just pathetic.
You were outplayed from start to finish, they dominated possession, had far more shots, had far more shots from dangerous positions and you were bloody lucky to even get a single point out of it.
I do love the fact that Liverpool are very quickly becoming a complete laughing stock, it's great.
