It is Khan's heart's desire to catch up with Pacquiao for the super-fight he has pursued for years, in the belief that it would define his career legacy.
One small problem: their promoters are not so keen on the idea, which has been born out of the PacMan's resurgent flattening of Lucas Matthysse in Kuala Lumpur on Saturday by which he claimed his 11th world title.
Bob Arum, still Pacquiao's man in the U.S. despite not promoting that WBA welterweight championship in Malaysia, would prefer him to fight Terence Crawford or Vasyl Lomachenko, both of whom, naturally, are in his Top Rank stable.
Eddie Hearn would rather Khan move on to a domestic dust-up with Kell Brook, which was his reason for adding our former Olympic hero to Special K in his Matchroom.
Of course it is easier for promoters to make fights when they have both boxers under their auspices.
For Arum, the incentive is to launch either Crawford or Lomachenko into the pay-per-view stratosphere on the back of Pacquiao the global super-star.
