Rovers boss felt his side had done enough to claim all three points but there is plenty to be worked on.
Henning Berg was disappointed that Rovers couldn't turn chances into goals as they were held to a draw by Birmingham City.
After a bright opening Rovers took a deserved lead, Ruben Rochina converting from the spot after Mauro Formica had been brought down in the box.
But Birmingham levelled almost immediately, Marlon King snapping up a rebound after Nikola Zigic had struck the post, and although Rovers then dominated for long spells, they weren't able to get that winning goal.
Speaking to Radio Rovers after the match Berg said: "At times we played the way we should do with the tempo, the quality, the right movement and getting the chances.
"What we lacked was the end product to finish the chances off.
"At other times we did okay and got into good positions but didn't have the right quality to make big chances.
"It was a mixed game for us, an okay game, we are looking at our pattern of play now, what we need to do is improve the tempo and the quality and make sure that the crosses and the finishes are a little bit better and if we had done that then we would have won the game.
"We should have won on Tuesday and I felt we were the better team today without winning and we don't want that to be a habit.
"We just have to show that we are improving we've some week's coming up now where we only play on a Saturday so it is possible that we can work on different things at the training ground."
