Wigan Athletic have confirmed that negotiations over the transfer of winger Antonio Valencia to Manchester United are expected to start "very shortly". United have indentified 23-year-old Valencia as one of the players they want to bring in as a replacement to Real-Madrid bound Cristiano Ronaldo with a fee in the region of £17 million ($28m) being mooted. Wigan chairman Dave Whelan told Press Association Sport that the Premier League champions have made their interest in the Ecuadorian international winger known for “the last two or three months”.
