Luis Suarez had a Manchester United clause written into his Barcelona contract, according to reports.
The clause reportedly prevented the 33-year-old from signing for the Red Devils on a free.
Suarez found himself forced out at Barcelona after club president Josep Maria Bartomeu left him off of a list of 'indispensable' stars.
The former Liverpool striker wasn't short of suitors, with Juventus among the clubs keen to snap him up.
The Serie A giants were favourites to sign Suarez subject to him passing an Italian language test, which he passed with flying colours.
But he was later accused of cheating on his exam, which put the transfer story to bed.
Atletico Madrid eventually stepped in and snapped up the Uruguay international in amongst the dust.
According to ESPN, despite the La Liga clubs being a direct rival to Barcelona, Atletico were not included on a list of teams Suarez was prohibited to join, per his contract at the Camp Nou.
Clubs on the list reportedly included: Manchester United, Manchester City, Paris Saint-Germain, and, of course, Real Madrid.
Suarez wleft Barcelona as the third highest goal scorer in the club's history.
He put pen to paper on a two-year deal with Atletico before saying his final goodbyes to Barcelona teammates.
Manchester United were tentatively linked with a move for the former Liverpool star at the start of the summer but never made a concrete bid.
