Bradford forward James Donaldson admits the players were disappointed to hear fans booing at half time of their opening day defeat against Catalan.
The Bulls were comprehensively outplayed by the French side, going down 34-12 at Odsal, to leave them bottom of the Super League table after the first round of fixtures.
Speaking via a blog on the club’s official website, Donaldson, 20, admitted the squad need to turn things round quickly for this weekend’s game against Castleford.
He said: “It was disappointing to hear the fans booing us at half time however we realise that the fans have a voice as well as the players and are well within their rights to show their opinions.
“We need the fans to get behind us as much as they can and support us, although we know that we have to give them a performance to cheer about.
“We have brought in some new players over the winter and were hoping for a new start this season but it never happened for us.
“The fans had some high expectations this season but we didn’t do what was needed and will need to make some big changes before the Castleford game this weekend.”
Bradford finished 10th last season, and ended the season in disappointing fashion, with Mick Potter admitting he wasn’t happy with how 2011 concluded.
