Amir Khan would 'out-box' Danny Garcia in any potential rematch, according to his trainer Freddie Roach.

Khan was floored three times by Garcia on the way to a fourth-round TKO defeat, but Roach, who also trains Manny Pacquiao, has backed Khan if the two square off again.

Roach told RingTV: "If we get a rematch, we will out-box him. I want a rematch right away.

"There is no sense in even thinking about 147(lbs) until we show that we can beat this guy at 140(lbs)."

Khan's defeat to Garcia came after he he had fallen to a controversial points defeat to Lamont Peterson in December.
