Kalvin Phillips has admitted he was left 'confused and disappointed' when Marcelo Bielsa first spoke to him about playing in a deeper midfield role.
The Leeds United star has been a revelation in the position this season during the club's push for promotion to the Premier League, having previously played in a more advanced role.
His performances have seen him being touted for a spot in Gareth Southgate's England squad, while he is also now widely regarded as the best player outside of the top-flight.
However, Phillips has admitted that he wasn't initially swayed by Bielsa's idea for his new role - but added that he could not refuse his Argentine boss.
"I was surprised at first. The season before he arrived, I’d scored seven goals, so I was a bit confused and disappointed when he spoke to me," he told FourFourTwo.
"I could hardly say no, though, could I?! Especially given his track record of improving players. He saw something in me and offered to teach me how to play a different role.
"I’ve adapted well, although he’s never completely satisfied! He’s always saying he thinks I can improve. That can sometimes be frustrating when you think you’ve played well, but those are the standards he sets."
Leeds have seen their push for promotion halted by the coronavirus outbreak but, having suffered heartbreak last season, the club have been spurred on with their objective.
"We’ve massively improved in this campaign; we’re a lot more experienced. We went through a bad patch at the wrong time last season, and then lost in the play-offs. It was tough, but it helped us."
