Nketiah's season-long loan to Leeds was confirmed on Thursday afternoon, shortly before the close of the summer transfer window.
The 20-year-old had been linked with the Whites' Championship rivals, Bristol City.
But the Independent reported on Wednesday that he was likely to snub the Robins in favour of a move to Elland Road.
The newspaper cited the relationship between the Arsenal manager, Unai Emery, and Leeds' director of football, Victor Orta, who were colleagues at Sevilla, as a deciding factor.
And their capture of Nketiah now looks an even bigger coup for Marcelo Bielsa's side, assuming the Independent's latest update is accurate.
The former Chelsea youngster has been signed to fill the boots of Kemar Roofe, who was sold to Anderlecht this week after scoring 15 goals in 34 games last season.
