Both teams have reached the Europa League round of 32, though Slot was angry after their 4-0 reverse.
“An annoying phase after halftime? That is an understatement," snapped Slot, as United fired three goals home in the space if 15 second-half minutes.
"That may reflect the qualities of the opponent, but the most important thing is: you can play along nicely, but you can also give the game away in a few minutes.
“Now in the group phase the result is not that important, but in the knockout phase it is. If you then lose 4-0 and you still have a return leg...
“We came here to win, and we didn't succeed. But the disappointment is not that great, because we are in Europe."
