Manchester United have committed an extensive catalogue of transfer mistakes over the past decade, but they can take some comfort from knowing they weren't responsible for the worst transfer decision in the Premier League during that time.
Angel Di Maria, Romelu Lukaku and Paul Pogba are just a few examples, that's without mentioning Alexis Sanchez and his cringe-inducing unveiling playing the piano, but those mistakes weren't as grievous as Chelsea giving Kevin De Bruyne just eight games at the club before selling him to Wolfsburg for £18m. De Bruyne has since made a mockery of Chelsea's miscalculated assessment.
Chelsea deemed De Bruyne not good enough and yet he's been among the world's top three midfielders for most (if not all) of the seven years he's spent at Manchester City. United are all too familiar with De Bruyne's quality. He's an architect under Pep Guardiola.
