Bremen only narrowly avoided relegation in their worst season since Thomas Schaaf took charge in 1999, culminating in a parting of ways with the longest-serving coach in the Bundesliga.
They have failed to qualify for Europe for three seasons in a row but Junuzovic feels Bremen are set for a much better season in 2013/14.
"I'm particularly optimistic because I have the feeling that the whole squad is looking forwards and we are joined by positive thoughts," he said.
"There is a transformation occurring. There is a good blend of relaxation and total concentration and if we can maintain this throughout the entire season, then that would be great."
Bremen's main priority is ensuring last season's relegation battle proves a blip.
"All I am hoping for is that we avoid such a stressful season," the Austrian added on his club's website.
"We want to get away from the bottom quickly, not chasing any dreams but collecting as many points as possible.
"If we can cement our place in mid-table, then that would be a good step."
