Harrison has shone this season on-loan at Elland Road.
He told the Manchester Evening News: "In the way we play, if you watched both teams, you would say so, but in terms of how the training sessions are conducted they're completely different, which is interesting because the outcome is the same.
"It's two different styles of training but when you get on the pitch some of the ideals and the way we like to play is very similar."
When the offer of a loan move to Leeds came about in the summer Guardiola told Harrison "it would be challenging but it would be good". He wasn't wrong.
"He's very different. He has a unique way of working and it's been something I've enjoyed adjusting to," Harrison said of Bielsa.
