VfL Wolfsburg coach Dieter Hecking believes that "small details" will be the determining factor in his side's Champions League clash with PSV Eindhoven on Wednesday.
Wolfsburg eased to a 2-0 victory over PSV in their last Champions League meeting on October 21, but Hecking knows that there is no room for complacency as Wolfsburg look to maintain their spot at the top of the Group B standings.
"We have to play our own game. Our aim is to progress to the next round and finish first or second in the group," he told reporters. "Tomorrow we can move closer to that goal if we win.
"We have to make fewer mistakes than PSV. Small details will be decisive."
Hecking is also hoping that Wolfsburg can build on their good run of form of late which has seen them win four out of their last five games, but is braced for an intimidating atmosphere when his side turn out at the Philips Stadion.
"At the moment all players are fit but we have one training session to go. We will go for the victory as always," Hecking said.
"PSV are strong and technically a good team. I was impressed by the great atmosphere at Manchester United [on matchday two], the crowd was fantastic. We have to be prepared for that again. PSV will do everything to go for the victory. I hope we can continue our current form and results."
