The Gers failed to get promoted to the top flight from the Scottish Championship at the end of the recently concluded 2014-15 campaign.
Rangers finished third in the ‘regular’ Championship season and reached the Premiership playoff final, where they were comprehensively defeated by Motherwell.
Collins believes that Rangers are not in the Premiership because they did not deserve to be.
“They're not in because they didn't deserve to be in," Collins told BBC Sport. ”Motherwell beat them in the playoffs so they've got a big season for them to try and win the Championship and get back in to the top league.
"Of course everybody knows Rangers-Celtic games are special, they're exciting to be involved in, but it's up to Rangers now to try and win that Championship, get promoted and get back in with us.”
Can Rangers win promotion next season?
Rangers remain a big club in Scotland and will be aiming for promotion to the Scottish Premiership next season.
The Gers have a new manager in Mark Warburton, who took modest Brentford to a top-six finish in the English Championship in the 2014-15 campaign.
The Glasgow giants have a lot of work to do in the summer, especially in the player recruitment department, but they will still be one of the favourites to win the Championship.
