One of the commentators on BBC Humberside said that W's whole game is more or less corners, free kicks and long throws. Hmmm, I think a few (most?) of their goals came from open play against County.
Wrexham's game is wholly based on getting set pieces, at which they are very effective, and they are very direct with virtually no midfield interplay. They have scored 15 goals from the long throws this season so ironic that the winner came from a Grimsby long throw.
