The negative reactions are completely reasonable. You say it yourself, and you are right, that he has been dreadful in the past few seasons. I would go further and ask; when has he ever been good?
Is he a player who possesses the qualities that a club with top 4-5 ambitions should have? The answer is pretty obvious.
By that logic we can't criticize the performance of any footballer, athlete, politician, actor, musician etc etc. Then why do we have this forum, if not to voice opinions, positive or negative?
I agree about Almiron/Murphy, but our priority should be a left back. I thought a LB would be the top priority during this transfer window.
I love Big Dan but he's not a left back, and definitely not someone who can fend off opponents in the top 6 of the PL nor will he be against CL teams.
