How is that a “careless challenge”? To even call it a challenge at all is a stretch. He just gets there first, takes possession of the ball and then stepped on the late arriving Chalobah as he turned upfield. Absolutely ridiculous to disallow that.
At least the lack of a priority window for displaced ST holders is something that, one would think, can be easily remedied by the next home cup fixture. Retooling the way the concourse is segregated is significantly higher hurdle.
