Rhodes netted a hat-trick in his side's 4-1 win over Peterborough this afternoon just a matter of days after scoring twice for Scotland.
Berg's side took an early lead in the match before Rhodes stole the show, and the Rovers boss believes that the 22-year-old will score goals for as long as he is given chances.
"It was a fantastic feeling to see my team produce a performance like that. Crystal Palace had needed two very late goals to beat Peterborough and Brighton had to score in injury time to do it, so going in front so early was key," said Berg.
"The difference between that display and our previous games was the quality of our play in the final third. We already know Jordan is a great finisher and he proved that again. He did brilliantly in League One last season and is already doing well in the Championship. Hopefully next season he will be in the Premier League with Blackburn.
"Providing we feed him with opportunities he will score lots of goals. It was a shame we conceded a late goal as that stopped it being a perfect day."
Rhodes has scored nine goals in 14 matches for Blackburn since joining for a club record fee this summer.
