The Ammies’ lead at the summit was reduced to two points last Saturday after they were beaten 1-0 at York City.
Salford face another tricky trip this weekend when they visit improving Alfreton Town and they know that another slip up could see them knocked off top spot come 5pm on Saturday.
Johnson’s side have only scored three more goals than mid-table Alfreton this season and the joint-boss wants to see some more comfortable scorelines.
“Some of the play (against York) was outstanding, some of the chances we created were fantastic but ultimately we’ve lacked that cutting edge in the final third and that was disappointing,” he told the club’s website.
“For a side that’s been top of the league for a large part of the season, we’ve not been ruthless enough. The lads need to start taking some more responsibility with that I think because in training we’re smashing balls into the net.
“But we’re top of the league, it’s not all doom and gloom. In the first half and even in the second half towards the end (against York), we cut them open.”
