Chelsea boss Enzo Maresca has had a pop at the scheduling before next week's Conference League final, with Real Betis set to benefit from an extra 48 hours' rest in the build-up.
Betis, managed by Manuel Pellegrini, have been allowed to play their last La Liga match this Friday night.
Chelsea, however, will face Nottingham Forest away on Sunday afternoon in a seismic Premier League finale which will determine who secures Champions League qualification.
Maresca believes UEFA should consider enforcing a rule which makes it so that both finalists play at the same time beforehand, rather than giving one team an obvious advantage.
