The Championship club, whose promotion bid ended in the play-off semi-finals last season, are second in the table behind leaders West Brom and will open up a 10-point gap between themselves and third-placed Fulham with victory.
'We cannot link this match with the disappointment of last season,' Bielsa told The Mirror.
Leeds manager Marcelo Bielsa has issued a rallying cry to his players ahead of their next game
'I don't think that last season the team couldn't cope with the situation. If there is something this team has shown every time they play, it is character.
'The eight matches that are left are going to generate the same expectation until the situation is defined.
'Every match is important. This has a more valuable meaning because we play with the direct and closest team to us in the fight for promotion.'

Leeds recently removed a cardboard cutout of Osama bin Laden from the stands at Elland Road after eagle-eyed fans noticed the image of the former al-Qaeda leader.
In a bid to boost stadium atmosphere, Leeds have allowed supporters to pay £25 for themselves to appear – in the form of cutouts – in the stands.
As a result, an image of a 'life-size' Bin Laden started to circulate on social media after one Twitter user spotted the cutout of the former al-Qaeda leader.
