Former World Champion Jeff Fenech believes Jeff Horn is more than capable of an upset victory over Manny Pacquiao.

The Brisbane school teacher will take on Pacquiao, one of boxings all time greats, at Lang Park in Brisbane on July 2.

Fenech (pictured), a world title holder in three divisions says if everything goes Horns way and he chooses the right approach to the bout, then an upset is definitely on the cards.
