Paris Saint-Germain were reportedly told to sell eight players or face expulsion from the Champions League.
Spanish outlet El Pais claim Uefa acted after complaints from Juventus, Real Madrid and Bayern Munich among others that PSG had broken FFP regulations.
It goes on to state that Angel Di Maria, Javier Pastore, Blaise Matuidi, Lucas Moura, Julian Draxler, Hatem Ben Arfa, Serge Aurier and Thiago Silva were transfer listed within 48 hours.
Only two of the players secured exits – Aurier to Tottenham and Matuidi to Juventus.
The double sale raised £41million for PSG, which hardly puts a dent in their incredible £198m Neymar swoop.
But it appears PSG’s quick reaction was enough to ensure they were allowed to take their spot in the competition.

And the Parisians initially signed Mbappe on loan, with a £162m price tag in 2018, to offset the costs.
The January transfer window comes around before the knock-out stages and the remaining six players may spark a Europe-wide bidding war.
Boss Unai Emery and his squad are apparently furious at the events, with the expendable players most upset.
PSG hammered Celtic 5-0 in their first European outing and face Bayern next in a mouthwatering tie, with the FFP row adding an extra dimension.
After the Neymar deal, president Karl-Heinz Rummenigge said: “During the Neymar transfer I asked myself the question what would be more important: Neymar or the Allianz Arena.
“‘I have to say clearly that I prefer having the Allianz Arena which is also more important.
“We as Bayern Munich must have a different philosophy.
“Overall the Neymar transfer could cost even more than the arena.”
Emery’s side are also top of the league – a point clear of last season’s shock winners Monaco.
