Southampton manager Claude Puel says his side's 3-0 loss to Everton was "difficult to accept" on Monday.
Substitute Enner Valencia came on in the second half, opening the scoring in the 73rd minute and winning the late penalty which allowed Leighton Baines to double their lead before Romelu Lukaku added a third for gloss.
The scoreline was as harsh on Saints as much as it flattered Everton in a game which was low on quality and Puel admitted as much after the match.
"It is difficult to accept this. Three-nil is too much to take. My players did not deserve this," said the Frenchman.
