CHAIRMAN John Berylson believes Millwall's battle against relegation last season will prove to be a valuable learning curve for the club.
The American insists the Lions will heed the warning signs from their disappointing campaign as they plan for the future.
"I think we learned a lot about ourselves," he told the club's official site.
"We learned how to run a Championship club and what we have to worry about in the future. We now know a lot about the other clubs and our players' abilities.
"For whatever reason, there were a lot of things we didn't learn this time last year. As we went into our meetings at the end of the season, it's interesting how different our agenda was from what it was in the prior year."
Boss Kenny Jackett has been busy in the transfer market since the season ended, with deals for Bournemouth wing back Scott Malone and Oldham winger Chris Taylor already in the pipeline, but Berylson says Millwall will take a sensible approach to their summer business.
He said: "I think there's some positions that everyone knows where we are weak, so we'll go out there and see who we can do something with.
"I like strikers so if there are more out there, I'll go and get them. I'd love us to sign more strikers. It's about identifying the holes and filling the team up. We want to play players in the positions they ought to be played – Kenny was forced to experiment last season.
"I think the fans and I have a different view – but I think getting players for the best deal is always the best thing to do. Where's the victory in paying over the odds for somebody and being disappointed?
"We've made that mistake a few times and we're very conscious of that."
