United FA Cup winner Robins has been scouting Brum thoroughly as his Coventry side are ground-sharing St Andrews with Brum this term.
And he can see why his old club are trying to buy the £30million-rated England U17 midfielder.
“In Jude Bellingham they have one of the best 16-year-olds or the best 16-year-old I have ever seen," Robins said.
“Bellingham is a stand-out. He is a brilliant talent capable of playing in the Premier League, no doubt about that.
“He is ridiculous for 16 years of age to have that power in his body, it is unbelievable.
“He has talent way beyond his years without a shadow of a doubt."
