David Wotherspoon says Hibernian are determined to climb out of their current slump and will approach the clash with Clydesdale Bank Premier League leaders Celtic in a positive frame of mind.
Hibs won at Rangers and against Motherwell in November, but have endured a winless run of six league games since and drew 0-0 with Irn-Bru Second Division side Ayr in the Scottish Cup last weekend.
"We're just not getting good results - it's as simple as that," said Wotherspoon.
"We're not hitting the top of our form, but the boys are showing the effort and desire to get there.
"I think we will eventually and hopefully that starts from Saturday.
"We're upset ourselves the way we play sometimes, but we're trying to do our best for the fans and for ourselves. We're trying harder with every game to try and get that victory."
