Bruno has called for unity between players and fans as Albion strive to get back on track.
But he admits the team need to improve if they are to have any chance of making the top six.
The Seagulls right-back felt Saturday’s 2-0 defeat by Middlesbrough came down to “details”.
But Bruno, below, added: “The important thing now is we all remain united.
“We need to give something so the fans are enthusiastic. As players, we need to be honest with ourselves and try to improve.
“We’re on a bad run but one good result will change everything.”
Bruno arrived at Albion in 2012 from Valencia, whose supporters are notoriously quick to criticise.
He added: “Since I’ve been here, if there is one thing that has characterised us as a club it’s that we have been very united with our support.
“There has always been a really good feeling. We need that now.”
