Mourinho's biggest mistake?
Chelsea's start to the decade was dominated by 'Red Devils' as the 'Blues' lured three famour Belgians (as the old joke goes) to the club in quick succession. Lukaku was the first through the door in 2011 as he continued his development towards becoming the "new Drogba". Hazard and De Bruyne followed a year later, each arriving with a burgeoning reputation as they looked to displace first-team stalwarts such as Frank Lampard.
However, Chelsea's policy with regrad to young talent in that era was very much the same as it is now, buy in bulk and loan them out at a premium to ensure a consistent source of cashflow and regular first-team football. Hazard was lucky enough to avoid this ritual, having arrived off the back of some scintillating Ligue 1 displays made him one of the most in-demand youngsters in world football. Lukaku and De Bruyne, on the other hand, were put through it and seemingly they failed the test.
Lukaku, now of Manchester United, joined Chelsea from Anderlecht, before being farmed out on loan to West Brom and then Everton. Eventually, he joined the 'Toffees' on a permanent deal after failing to completely convince Mourinho at Chelsea.
De Bruyne was not afforded as many opportunities. Had it not been for his status as one of the best in the world now, few would remember his stay at Stamford Bridge as he passed by in a flash before joining Genk and Werder Bremen on loan, before making a permanent move to Wolfsburg with just nine Chelsea appearances to his name.
Of three of the most talented Belgians to emerge in recent history, only Hazard fully convinced Mourinho as to his ability and potential. With Mourinho having since moved on a brought Lukaku with him to his new club, it would appear that he doesn't particularly regret his decisions, but Chelsea could be forgiven for thinking what might have been if they had kept hold of all three stars.
