Bromley have won three and drawn four of their games so far, beating Barnet, Cheltenham and Harrogate.
Whereas Oldham have recorded just one win and have picked up just one point at home.
Going into the season, Hewitt believed Bromley had a chance of pushing for the play-offs but after seeing the way they have played so far he now believes this is a realistic goal for the club.
“Since Andy Woodman came to the club, Bromley have created a style of play that is so hard to beat. That whole ethos permeates through the club that you’re going to have to play really well to beat Bromley – you can’t just turn up against Bromley and expect to get three points,” he said.
“Andy has succeeded in getting every single person on and off the pitch to buy into what he’s doing.”
Despite Bromley’s strong start to the season and their unbeaten record against the Latics, Woodman is expecting a tough test at Boundary Park.
“They’re a decent side. I don’t think their start, results or their position is really reflective of how many chances they’re creating and how well they’re playing,” he told Radio London.
“So it’s a really tough game for us, it’s never easy going to Oldham, the atmosphere will be particularly good and it’s a good test for us.”
