The Hammers snapped Antonio up from Nottingham Forest, after the winger showed impressive form in the second tier for a prolong period of time.
And the 25-year-old believes that there are plenty of other players plying their trade outside England's top flight, who would be ready to make the step-up, if given the opportunity.
“There is loads of quality players in the Championship,” he told London 24. “More scouts should go down there, give players a few games not just one or two. That is the main difference between the Premier League and Championship, being consistent.
“Teams get promoted because of consistency. The likes of Darren Randolph, Patrick Bamford, Bakary Sako, Tom Ince, you just need a chance.
“The Championship is maybe more hustle and bustle. If you can do it in the Championship then I think you can in the Premier League.”
Antonio scored four goals in his opening five matches for Forest this season, and if he can continue that form in the Premier League then he will be an important addition for the Hammers.
The wide-man offers them pace and power and he could be handed a debut in West Ham's match against Newcastle United later this evening.
Slaven Bilic's side take on Newcastle, looking to pick up their third win of the campaign, after showing their class to beat Arsenal and Liverpool already.
If Antonio does start, he will offer the side a different option, with his direct style contrasting nicely with the more intricate Manuel Lanzini and Dimitri Payet.
