Sheffield Wednesday have completed the signing of midfielder Billy Mitchell from Millwall [2], while a reported transfer for Sheffield United striker Danny Ings is said to have collapsed following his recent exit from the club [3]. There's also word that BAE Systems is planning an expansion in Sheffield as part of a bid to supply British Army vehicles [4], and Sheffield's council says a World Snooker deal could deliver a £200m boost to the city's economy [5]. I don't have further detail on any of these beyond the headlines.
