The reigning Premiers are back at the MCG to face last year's runners up in a highly anticipated Grand Final rematch between Collingwood and West Coast on Saturday night. 

Brad Hardie and Kim Hagdorn spoke to Collingwood's General Manager of Football on 6PR's Front and Centre and he says the key to a win tonight is in the midfield. 

"The game today certainly lends itself to midfielders because there's so much running, so much up and down," Geoff Walsh told 6PR.
