Hmm, could of sworn this was already discussed last summer during the takeover.
PIF have investments in several private equity firms not just Clearlake, of which they have less than a 5% stake in each one. Their stake in Clearlake is reported to be only 1.5%, of which the Premier League sufficiently investigated (during Newcastle/Chelsea purchase) that PIF's assets were outside of Clearlake's portfolio that included Chelsea Football Club's purchase.
