Manchester United boss, Louis Van Gaal, has urged his side to avoid complacency against Yeovil Town in the FA Cup.
The Red Devils travel to the League Two side on Sunday afternoon in their third round tie, however United have failed to win the trophy since defeating Millwall in the final 2004.
And the Dutchman knows from past experiences that you can't expect an easy win against lower-league opposition, using their 4-0 loss to MK Dons in the Capital One Cup as an example.
"We know from our early exit in the [League] Cup that league places mean nothing in the cups but I know that also from Ajax and Barcelona so it's not only like that in England," Van Gaal told reporters.
"It is always a shock when you play against a lower team because you can assume that you have to win but it is not like that in football.
"I have lost with Ajax against a lower team - against Cambuur, for example. I lost at Barcelona against a third-division team. I can't remember [which team] any more - it has been wiped out of my mind - but we have lost."
