The Poppies’ displays have, in general, been impressive since Cox took charge of the club at the beginning of November.
Having been in the bottom two of the Vanarama National League North when Cox arrived, last weekend’s 1-1 draw at Altrincham saw them move seven points clear of the relegation zone.
Cox was impressed with his team’s display at Moss Lane as they held the in-form Robins to a draw.
However, the Poppies are now without a victory in their last four league matches.
And, as they prepare to entertain Cox’s former club Guiseley tomorrow (Saturday) before hosting Hereford next Tuesday, the Kettering boss is hunting a return to winning ways.
“I think now, we need to be looking at those three points,” the Poppies manager said.
“We have been quite good on the road and we picked up the point at Altrincham but what I want to see from us now is to be brave and grab hold of the games when we are at home.
“We have got two home matches but they are of no use if we don’t maximise the results from them.
“When I look at the performance levels, I think there’s been a real consistency about us aside from the home game with Altrincham when everyone had the right to question our mentality.
“I am just looking for that ruthlessness now.
“We are creating chances and, as much as we talk about performance levels being good, we still need to be more ruthless as a group.
“We have been on top in games and when that happens we need to make sure we take advantage of it.
“I think we are heading in the right direction but I am asking for more. We have to take advantage when we are at home.”
The Poppies are set to be boosted by the return of Marcus Kelly following a hamstring injury but Michael McGrath is set to miss the next two games after picking up his 10th booking of the season last weekend.
