Youngest combined age of boxer/trainer to win a world title

[Enlightened-One]

Canelo's trainer looks pretty young. not sure how old the dude is but he looks like hes in his 30s and canelo was young when he won his first world title.

Eddy Reynoso was 34 years of age when the 20-year-old version of Canelo captured his first world title. However, Eddy’s father, Chepo, trains Canelo also. So I’m not sure this really counts.

no but they never won a world title together yet

Damn I didn't read it right. For some reason I thought it was fought, not won. My bad.

(If you will count WBA Interim or IBO) Chris Eubank Jnr - 'self trained'
