Chelsea finally completed their swoop for Wigan forward Victor Moses on Friday after the Nigeria international passed a medical and agreed personal terms with the European champions. The Blues had seen four bids for Moses rejected by Wigan chairman Dave Whelan during the course of a fractious transfer saga that had lasted since the end of last season. Whelan had infuriated Chelsea by speaking publicly about the negotiations in a bid to drive up the price. But Chelsea boss Roberto Di Matteo got his man at the fifth attempt after Wigan confirmed on Thursday that they had accepted an improved offer, believed to be around £9 million, for the 21-year-old. “Chelsea Football Club is delighted to announce the signing of Victor Moses from Wigan Athletic,” a statement on the club’s website confirmed. Chelsea didn’t announce the length of the contract for Moses, who joined Wigan from Crystal Palace in 2010 and rose to prominence after a series of impressive displays for the Latics last season.
