Rob Page expects loan pair JJ Hooper and Kenji Gorre to push hard for starting roles at the Cobblers following their midweek 'supersub' exploits.
The duo played a key role in Town's 3-1 victory at Swindon Town, adding an attacking threat when it looked like the home side were going to be the most likely to push for a win after equalising to make it 1-1 on 67 minutes
After John-Joe O'Toole had headed the Cobblers back in front on 76 minutes, Hooper and Gorre combined, along with a little help from Alex Revell, to seal the win on 82 minutes.
It was Swansea City loanee Gorre who took the plaudits as he netted, hammering home after Revell had dummied Port Vale striker Hooper's low cross from the right wing.
Page was delighted with their impact, and expects to see more of the same as the pair aren't at the Cobblers 'to make the numbers up'.
Gorre has found himself out of the starting line up in the past two matches after being an ever-present for the first eight fixtures, while Hooper has yet to start a league game.
"I have two hungry players that haven't come to the football club to make up the numbers in the squad. They have come to play games," said the Cobblers boss.
"JJ has come in, he was being played out of position at Port Vale and was frustrated, so he has come in here because he wants to play up top.
"He knows I have got Marc Richards, Alex Revell, who has been outstanding lately, so JJ knows he has to be patient and wait for his chance.
"Given and opportunity to come on, I ask him to do what he did the other night, and that is play a hand in the third goal for us.
"It's a similar story for Kenji. I left him out last week, and on Tuesday, from the starting line-up, and he has a point to prove as well.
"When he comes on he knows he has to make an impact, and scoring a goal is a great way to do that."
Both Gorre and Hooper are likely to start on the bench again this Saturday when the Cobblers take on Bristol Rovers at Sixfields (ko 3pm).
Another player who could be joining them in the dugout is Jak McCourt.
The midfielder missed Tuesday's win at Swindon after he suffered a concussion in Saturday's win over Southend United, but the Liverpudlian is expected to be fit for the weekend.
Page then has to decide if he brings him straight back into the team, or sticks with the 11 that won at the County Ground.
