Manchester United defender John O'Shea knows Schalke's fans can be a factor in their Champions League semi tomorrow.
O'Shea also knows Schalke's fanatical supporters tend to generate a hostile atmosphere in the Veltins Arena - where Wayne Rooney was sent-off during England's World Cup quarter-final defeat to Portugal in 2006 - although after squeezing past Marseille in the last 16 after a goalless first encounter, he is not convinced United's hopes of overall success hinge on them grabbing an away goal.
"We have to use our experience to quieten their crowd down," he said.
"An away goal is always nice but it is not the be all and end all.
"We know if we are in sight when we come back to Old Trafford, we will have a great chance."
