Nketiah was loaned out to Elland Road this summer in search of more regular playing time to continue his development. But despite scoring four times in nine appearances in all competitions, the 20-year-old is yet to start a Championship game, with Bielsa sticking by Patrick Bamford.
"For me it is very important that Eddie has a good spell at Leeds," Bielsa said.
"If Nketiah doesn't do well here in Leeds, the responsibility is going to be mine. That will be fair because Nketiah is a player full of results and as coach, I have to know how to manage all this skill to improve the team.
"The person who most wants Nketiah to have success at Leeds is me, but also I value Bamford, I value him a lot."
