The 19-year old has highlighted the physical demands of the Premier League.
Three substitute appearances is the sum total of his contribution this season, with one coming in the 2-2 draw with Chelsea at St James Park, and he will hope to add to that as the campaign progresses.
Toney was signed with a view to the future however, and has excelled in the Magpies’ Under-21 team, picking up the U21 Premier League player of the month for September.
"If you're not sharp, you're not involved," he said, in an interview with BBC Radio Northampton.
"I wouldn't try to disrespect the League Two standard, but they are sharper (mentally) and know what they are doing a lot more.
"You're trying to get stronger every day, especially at that level you need to be strong and fit, and that's the main thing I'm working on."
The physical aspect of the game is the side players are most in control of and enough hard hours in the gym should have the 19-year old up to speed in no time.
His natural ability isn’t in doubt and hopes are high on Tyneside that they may just have their hands on the latest gem to grace St James Park.
