Boxing: Picture Calzaghe - seven-year reign.

WBO super-middleweight champion Joe Calzaghe insists he deserves greater credit for his achievements than former champion Chris Eubank.

The Welshman will equal Eubank's record of 15 title defences if he defeats American-based Egyptian Kabary Salem at Ingliston next month.

Calzaghe beat Eubank in 1997 to take the vacant WBO title and has remained unbeaten since then to take his career record to 37 fights with no losses.

The Newbridge fighter will make history with the first-ever world title fight in Edinburgh but insists he has taken a far longer road to the top than Eubank.
