Loser, I'd say that comes with the lack of success with him, what he absolutely is though, is a liability, and the two both come together in one form: failure.
There is less sentiment in football than there has ever been and the decision on him has to be made quick.
Its not about being ruthless, its just commons sense. We could even say its taking him out of the spotlight to remove the pressure, whatever, but he has to be removed from the team immediately. Unless of course, which what does worry me - is Klopps misguided loyalty in players he believes will come good, they won't.
If you or I had that scully moment and got a game and we were so shockingly bad, which he has been on numerous occasions, you or I love the club enough to walk away. This lad has to be put out of his, and our, misery. Sadly the only person that can do that, may just prolong the agony for us all.
