Jose Riga says Blackpool have plenty of work to do after their third defeat in a week.
Rudy Gestede netted either side of half-time at Bloomfield Road, although Blackburn Rovers were forced to sweat for 37 second-half minutes as Tomasz Cywka pulled one back for a fully-stocked Blackpool.
The hosts fielded a full squad for the first time this season but are still searching for their opening win, while Blackburn got their campaign up and running after starting with a draw and a cup defeat.
“We showed fighting spirit and at times quality in that match. Spirit and mindset are important attributes but the play and the way we do things to create opportunities is huge,” said Riga.
“If we’d scored a second I don’t think people could have complained. Physically we are not ready yet and we don’t have enough players still, but the fans and the mentality of the players is good.
“Some players arrived only a couple of days ago and it’s a difficult situation. This is our third game of the season and we’ve only had one friendly against a team who aren’t at this level.
“We showed our players certain phases of play that we expected but we couldn’t always adapt to that because they just haven’t played with one another enough. But that will come, I believe it will.
“I need more players but I need quality and that is important.”
