Tony Mowbray was left frustrated after his side suffered a heartbreaking late defeat at home to Norwich City.
Teemu Pukki's goal with five minutes to play ensured Rovers suffered a second league defeat at Ewood Park in 15 months.
That was the difference between the two sides, but Rovers had chances of their own, most notably through headers from Derrick Williams and then Danny Graham.
And speaking afterwards, the boss was left ruing his side's luck against the Canaries.
“I thought we played pretty well against a team up there at the top of the table and had chances to win the game," he said.
“We knew they would have a lot of possession and the way they play. We had the best opportunities in a tight game and we’ve come out the back end of it with a defeat.
“I could easily be talking about a 1-0 win for us or a 0-0 draw, and we’re frustrated and disappointed.
“We’ve put a lot of work into today’s match and we pretty much ended the game with 10 men in the end after Harrison Reed picked up an injury late on.
“The inability to cover areas of the pitch, which we did so well for 85 minutes was the difference in the end.
“I feel it was an opportunity missed for us today. It’s frustrating.
“We have a squad of players and each needs to understand the required work ethic. We’re in tomorrow, see who we have available and move onto the next game."
