Slaven Bilic was sacked by West Ham in November 2017 as the club's owners felt change was necessary in order to move forward positively.
How painful it must have been then for David's Gold and Sullivan, even watching on from the comfortable seats in the directors' box, to see Bilic return to West Ham and show it his new side, Championship leaders West Brom, who are heading in the right direction.
And, potentially, the opposite one to West Ham, now led by the Croatian's successor David Moyes.
With a second string team and 10 men for the final 22 minutes, West Brom dumped West Ham out of the FA Cup in a bit of sweet revenge for Bilic.
