Dundee manager John Brown has identified James McFadden as Motherwell's biggest threat.
The Dees host the Well on Saturday and Bomber feels that the former Everton and Birmingham City forward holds the key to the visitors hopes.
"They've got a few flair players and none more so than McFadden," Brown said.
"If he's given time and space he can hurt you with his quality.
"It's something I keep going on about.
"I'm not asking our players to kick lumps out of the opposition, but if you don't give them space it's difficult for them to play."
