Yeah, it was all Barkley's fault. Even when he wasn't on the pitch.
Barkley has so far too much ability to be performing so abjectly. That's the difference. Mirallas, Valencia etc haven't got an ounce of the talent. But their performances are not much different.
Barkley is yet another of our talented youngsters who just simply hadn't the mental strength to succeed. He won't be missed, which is a shame. As long as we replace him adaquately with quality, and a better mentality.
