Bielsa has helped Leeds back into the Premier League and potentially the club's first top-half finish in the top flight since 2001-02.
But the Argentine said: "I have always said the dimension of the institution at Leeds is very big.
"The sporting past of Leeds is full of high points. To win four games in a row in the Premier League [if they win on Monday] compared to all the things Leeds has achieved, of course it would give us great happiness, but if you compare it to the past, it's not so big.
"To be able to be at the height of the past, some extraordinary things need to be done and we are quite far away from that."
Leeds meet Liverpool on Monday night.
