Former Texas A&M Aggies quarterback Johnny Manziel has stated that any team which passes the opportunity to draft him will regret doing so.

Manziel is expected to be a top-10 selection when the 2014 Draft begins on Thursday, with teams such as the Jacksonville Jaguars and the Cleveland Browns rumoured to be looking at options for quarterback.

He told reporters: "I believe they will [regret not choosing me], personally. I know in my heart how good I want to be and how committed I am to this game.

"I see there's room for me to improve, but to say I'm just a backyard-football quarterback, I don't think you do what I did in college and do some of those things.

"I don't think that's extremely fair. I hear it, but for me, I know it's all about my work ethic and my will to get better. That's very alive and inside me. I don't want to be what I was in college. Obviously, I want to be better."

Manziel won the Heisman Trophy in 2012, and broke a number of records during a glittering college career.
