Nketiah impressed during pre-season for Arsenal but opted for a move to Leeds on a season-long loan.
He already has three goals to his name – all from the bench – for Marcelo Bielsa’s side.
Nketiah says he went against pleas from Emery to stay at Arsenal in favour of joining the push for Championship promotion with Leeds.
“The manager wanted me to stay so it’s really confidence-boosting for me that he had me in his plans,” Nketiah told the Daily Mail.
“But I felt like it was a good step for me to come to Leeds.
“I hope it’s a good year that can leave me in good stead going back to Arsenal to fight for a place.
“There were a lot of options, there were options for me to go to Germany but me, my family and the club decided Leeds was the best place.”
