Evangelos Marinakis will be watching with interest as UEFA holds a two-day summit this week to discuss "potentially seismic rulings" about multi-club ownership.
Marinakis, who owns Nottingham Forest and Olympiacos, is part of a growing trend for individuals or businesses to oversee clubs in clubs in different countries - and that is leading to increasing questions about transparency and the integrity of competition, particularly in European cups.
Now, as Chelsea's takeover over Strasbourg brings the situation to a head, UEFA Club Financial Control Body has a decision to make about whether to tighten, relax or keep the status quo. As it stands, if clubs who have the same owner qualify for the same competition, the lower-ranked side is disqualified.
