Manchester United are readying a move for Borussia Dortmund defender Marc Bartra in the summer transfer window, according to reports in Spain. Bartra has only made 31 appearances for Dortmund since joining the Bundesliga giants last summer but the 26-year-old is being heavily linked with a big-money switch to Old Trafford ahead of the 2017/18 campaign. AS claim Jose Mourinho believes Bartra is an ideal fit for his starting XI and is keen for United to make an offer for the ex-Barcelona centre-back in the coming months.
