The 21-year-old has been given an overall rating of 84 in the game, which puts him in the top 100 players in world football and on level terms with Liverpool's Sadio Mane and Juventus midfielder Sami Khedira.
"To be honest I don't think I'll use myself in the game because I don't think my rating is very good," Alli is quoted as saying by Sky Sports News. "I'm going to refuse to play with myself until I'm a little bit more realistic."
Arsenal winger Alex Iwobi was also unimpressed with his overall 76 rating, saying: "I'm not happy with my stats either. They are the same as last year, that means there's no improvement."
FIFA 18 is due for release next Friday.
