"Everybody says the league position does not lie, but we have games in hand on most teams and have also had a lot of injuries," Jacobson told the club's official website. "There have also been a lot of players coming in on loan so it has been difficult to get a stable side.
"A lot of the injured players are back and I think that showed with the performance against Walsall. It proved that when we have a solid team we can produce wins."
But Oldham will have to be at the top of their game if they are to claim successive victories, with tough games looming against promotion hopefuls Colchester, Leeds and Norwich.
He added: "We are going into the games full of confidence and want positive results. We will not be going along to make up the numbers."
