Wrexham lost 2-1 at home to Birmingham in the Championship, and boss Phil Parkinson wasn't interested in excuses. He called the goals the club conceded "unacceptable" and said he felt "shellshocked" by how they came about. The loss stings because Wrexham controlled stretches of the match but couldn't capitalize on their chances while getting burned defensively. Parkinson's harsh self-assessment signals he expects better from his players in this promotion push. The defensive lapses are the kind of thing that derails a season if the team doesn't tighten up fast. Wrexham came from the National League last year and made noise early, but dropping points at home to direct rivals like Birmingham with sloppy defending is a recipe for disappointment come May.
