Leeds United midfielder Matuesz Klich admits he appreciates how manager Marcelo Bielsa has improved him.
Klich enjoyed an impressive first season in the Premier League last term.
He told the Leeds match programme: “I think he has improved every player and we seem like we can we play on 150% of our capacity, because we all played the best football in our lives and we are all in the best physical condition. We've never been running so much, we've never run so quick. And this is very good. And this is probably thanks to him.
"So yeah, it's a very enjoyable time, but he always feels there's a place for improvement.
“I think everything I did before he came I did on a slower pace. And now everything that I do, I look quicker, I move better on the pitch, and I know what my role is within the team more clearly. So I just do my tasks every weekend - every one of us has tasks, and if everyone does well then we win."
