Dan Walker and guests look ahead to the weekend’s football, including the opening day of the new Premier League season. Champions Chelsea begin their campaign against newly-promoted West Brom, while Blackpool’s first top-flight game since 1971 is away to Wigan. In the Championship, Sheffield United host QPR in a match that sees former Blades boss Neil Warnock return to Bramall Lane. North of the border, Rangers begin the defence of their SPL title against Kilmarnock.
