Bruno admits Brighton will need to take a serious look at themselves this summer.
The Seagulls's capitulation in the second-half of the season has them in danger of being relegated.
However, if Cardiff lose to Crystal Palace on Saturday, Brighton will be safe.
Bruno told The Argus: "For some time, the team hasn't been performing at the level which it should.
"We need to finish the season in the Premier League, save ourselves and from there do an in-depth analysis of what we need to improve.
"What hasn't worked? A lot of things. We as players need to look at ourselves and how we can improve in all aspects.
"Look at the stats, look at the matches, everything."
