The Bees are up to fourth after extending their unbeaten run to eight league games with a 3-2 win over fellow promotion hopefuls MK Dons on Saturday.
They fell behind twice but eventually secured another three points when Clayton Donaldson grabbed the winner a minute from time.
"MK Dons have a small squad but one that is high on quality," said Rosler.
"They play the same way week in, week out with the same players and are one of the best teams in the league.
"At times I feel they play games when they are not at their physical peak. I felt we could put them under pressure.
"I felt the longer the game went on, we would overtake them and that is what happened."
