I've never seen a footballer so affected by criticism than Barkley. His confidence just disappears.
....I'm not so sure this is the reason but if it is his character is lacking. Regardless, there are too many excuses. As RK said, it's up to him to produce quality displays week in week out, it's what the best players do. We know he can positively impact games, we want him to be a success but it's up to him to deliver.
