You want to minimise the mistakes he makes that cost us goals then that's up to you.He was the defender marking Armstrong for the goal we conceded.
The reason fans don't seem to rate him is because the small number of negatives or mistakes are very obvious/easy to see (like marking Armstrong for the goal).
vs. the very large number of positives (based on actual stats) are the boring ones that nobody really notices in-game.
It's not just his defending. It's his sloppy play in possession.
The sheer quantity of sloppy moments he has. Mis controlling the ball, heading it straight up in the air, slicing clearances. He's a total calamity at times.
He can drive forward and knock a decent ball across but apart from that he's such a sloppy footballer.
