Leeds United winger Helder Costa is yet to make a start in the Championship since moving to Elland Road.
Costa has been used sparingly by Leeds since his move from Wolverhampton Wanderers in the summer.
The tricky winger has not made a Championship start yet, but Bielsa is planning to bring him into Leeds line-up tomorrow.
With Pablo Hernandez out injured, much of the creative burden will fall on Costa’s shoulders.
But Bielsa is convinced that Costa can thrive with that responsibility for Leeds.
“Pablo Hernandez is not able to play. He has a problem, a muscular problem. He felt that warming up in the last match, but today is not good,” Bielsa admitted.
“He’s not well enough to play. Helder Costa will play. He is ready, he is prepared. I cannot say I am happy because people will say I’m happy Pablo cannot play!
“I am happy for Helder and sad for Pablo. I do not want to take the risk, but I am happy Helder is playing.”
Costa’s inclusion in Leeds’ starting line-up could be hugely exciting, as he has already shown his quality off the bench.
The Portuguese attacker has proven to be an excellent impact substitute this season, but he now has a real chance to nail down a place in Bielsa’s starting line-up.
Costa has previously proven himself to be a huge threat at Championship level, and if he can get back to his best then Leeds would benefit hugely.
Leeds currently sit at the top of the Championship table, but their results have slowed slightly after what was a blistering start.
