You may recall over the summer there was a controversy surrounding Crystal Palace and its qualification for the UEFA Europa League.
According to UEFA's rules, Palace was demoted to the Conference League tournament because Lyon, a club in the Ligue 1 in France, is partially owned by John Textor, also a controlling owner at Palace.
The law dictates that if "two clubs are in violation of the MCO regulation, the team that finishes higher in the league will play in the European competition. Even though Palace (12th) won the FA Cup and Lyon (sixth) only qualified on a technicality, the league placing alone determined the right to play."
UEFA has come out and stated that they will continue to hold firm to this rule, with clubs who might find themselves outside of compliance having until March 1 of next year to shift ownership if they expect to attain European football next season.
Consequently, Lyon currently sit atop the Europa League table, while Palace sit in 18th in the Conference League, which would send them into the knock-out phase of the playoff if the competition ended today.
All of this, of course, could impact Everton because the Toffees are part of a multi-club ownership model under The Friedkin Group, who also own AS Roma in Serie A in Italy.
As of now, that isn't an issue, since the rule only impacts clubs under the same ownership if they qualify for the same competition.
Roma is currently 4th in Serie A, with aims to return to the Champions League, while Everton's 7th place in the Premier League might earn the Toffees a Conference League berth if the season ended today.
Last season, 7th-place Nottingham Forest qualified for the Europa League, partially due to the Palace fiasco, but also because 17th-place Tottenham earned a spot in the Champions League because they won the Europa League last year. That doesn't answer many questions because of the odd nature of qualificiation, but it is something to watch.
The season is long, and there's no guarantee that Everton will retain its top-of-the-table position or even sniff Europe when its all said and done. But given the state of their ownership situation, it will be something to monitor.
