The 26-year-old striker has scored 21 times in 30 appearances and is set to fire the Magpies to promotion back to the Premier League at the first attempt.
And Bentley was impressed by what he saw from the former Crystal Palace man when the Bees faced Rafa Benitez's side this season.
“I think Dwight Gayle was one who springs to mind. He's a class player and will play in the Premier League next year.
“That's assuming Newcastle continue in the way they are for the rest of the season.
“Shelvey again, his range of passing was, quite frankly, ridiculous. I've not seen anyone pass like him, apart from Josh McEachran of course.
“Britt Assombalonga is someone I know personally who perhaps didn't play to his potential against us and he's a real handful.
“Kodjia at Villa is excellent. Hourihane is an excellent player. The list is endless. There are so many good players in the division.
“Sone Aluko was a good player. Tom Cairney – good player. They're our rivals but there's no doubting their ability.
“There's a lot of very good players – Forestieri at Sheffield Wednesday. I could go on forever.”
When it comes to Brentford's player of the year, Bentley knows it will be another difficult choice.
He added: “I've not thought about it too much. I'm not going to say who. There are lot of candidates.
“Maxime has been consistent, John, Harlee, Nico have been consistent. McEachran has been class when he's come in.
“Jota has come back and will no doubt clean up from the fans as they love him. Lasse, of late, has been excellent.
“Woodsy has been excellent. It's good that there isn't a runaway candidate as it shows it's a team effort so that's great.”
