Wolves head coach Nuno Espirito Santo has appealed to the Premier League to give teams in Europe an extended break to protect their players.
The Molineux boss has echoed Chelsea manager Frank Lampard in suggesting squads will need more time to recover from their European exploits.
Wolves host Olympiacos on Thursday in their Europa League last-16 tie having drawn 1-1 in Athens in March.
They could play until August 21 if they reach the final and, with next season's Premier League campaign due to start on September 12, Nuno feels players need to be looked after.
