The sheer competitive nature of the division means only nine points separate fourth-placed Kidderminster Harriers and Kettering Town, who are down in 15th spot.

“You only have to look at Southport.
“They were bottom of the table not that long ago and now they are in a play-off position.
“I might be wrong but I don’t think they have lost since we played them in the FA Cup.

“There are other teams as well and it just shows how competitive this league is.”
