Joshua is just shy of three months older than Prenga, but their careers have followed very different paths. After winning gold at the 2012 Olympics, Joshua turned professional the following year and went on to become a two-time heavyweight world champion. Joshua won each of his first 16 fights inside the distance in a run that culminated in him beating Charles Martin to claim the IBF title. Prenga made his professional debut three years after Joshua and won his first four fights by knockout. The Albanian fell to his first and only loss in his fifth bout and steps into the ring on Saturday on a 16-fight winning streak, although he does not have any recognisable names on his record.
