The coronavirus crisis continues to challenge decision-makers in football's corridors of power and could soon leave some of the game's biggest clubs facing contract conundrums.
Manchester United, Milan and Paris Saint-Germain are among the major European outfits who are due to farewell high-profile players when free agency comes into force on June 30.
Domestic leagues across the world appear increasingly likely to run beyond that deadline, meaning sides up and down the divisions could be forced to renegotiate deals beyond the typical expiry date.
It remains to be seen how governing bodies will approach the unfamiliar territory but Edinson Cavani, Mario Gotze and Zlatan Ibrahimovic will be watching closely like dozens more across Europe's top five leagues.
These are the stars and solid supporting cast members whose contract situations are worth monitoring in England, France, Germany, Italy and Spain.
