Input: Matt Lowton is wanted by Burnley as Sean Dyche plans for life without Kieran Trippier. The Aston Villa right-back is likely to leave the club after three years, with Premier League newboys Norwich and Middlesbrough interested. Derby County have also looked at the 26-year-old. Tim Sherwood has begun reshaping his squad with the probable arrival of Micah Richards on a free transfer and Lowton would like to move to get regular football. The Villa manager is a keen admirer of Trippier, who has a £3.5m buyout clause, and Burnley looked at a part-exchange involving Lowton. Villa could still move for Trippier even if the Richards deal goes through - Sherwood wants defensive reinforcements - but Tottenham and Liverpool represent more attractive options for him.Burnley look likely to lose Kieran Trippier to Liverpool or TottenhamThey want Aston Villa's Matt Lowton in as a replacementSean Dyche needs to build a squad capable of challenging for promotionTransfer news: CLICK HERE for all the latest
