Ruben Amorim believes the best preparation for Manchester United ahead of the Europa League final would be to shock Chelsea in Friday's Premier League clash rather than resting his key players.
United sit 16th in the English top flight, just outside the relegation zone, after their worst ever Premier League season by some distance.
Amorim has won just six of his 25 league games since taking charge in November.
However, the Europa League offers the chance of salvation with a place in next season's lucrative Champions League on offer for the winner as well as a major European trophy.
