He was offloaded by the Blues in 2014 but a lot has changed since then. Four years ago, Kevin de Bruyne was considered surplus to requirements by Jose Mourinho and sold to German side Wolfsburg for a fee believed to be around £17.5milllion.
The midfielder has since returned to England with Manchester City and has scored 11 goals and racked up 19 assists already this season to help Pep Guardiola's side set the pace in the Premier League.
In this summer's World Cup in Russia, Hazard will lead a star-studded Belgium side. When asked by 'COPA90' which of his compatriots he would like Chelsea to sign, there was no doubt in his mind: "Kevin de Bruyne."
When it was put to Hazard that the Blues already had him, Hazard continued: “Yeah I know. Go on, I’ll give another one - Radja Nainggolan. He’s good, he’s good.”
