Andre Ward has seen Amir Khan improvement under Virgil Hunter

Andre Ward believes that Virgil Hunter's training will see Amir Khan to victory against Carlos Molina on Sunday.

Khan fights the unbeaten Californian in the early hours and Ward believes that the switch of trainer following the defeat to Danny Garcia in July will be the key to his clash with Molina.

"I've seen an improvement [since the change to Hunter], he's listening and willing to learn and that has been his first step," Ward told Sky Sports News.

"I think he's going to pull through in a big way. He only knows one way to fight, he's very eager and very zealous but [under Hunter] a little more patient and you're going to see a better Amir Khan."

Khan has lost his last two fights and has said he may quit the sport if defeated by Molina.
