John Askey talks about the importance of the goal difference.


Port Vale prepare to play promotion-chasing Mansfield tomorrow afternoon.

The Vale will be looking to build on the point they picked up at Notts County last weekend.

Where despite not finding the back of the net, they kept a clean sheet, which was vital to ensure they have one of the best goal difference out of the teams towards the bottom end of the League Two table.

Port Vale have a goal difference of -14 while, Cambridge United are on -22 and basement club Notts County are on -32.

You can hear more from John tomorrow during our Saturday Sports Show tomorrow afternoon from 2 pm.
