Riyadh, Saudi Arabia: Mexico's undisputed super middleweight world champion Canelo Alvarez promises his title bout with Terence Crawford in Las Vegas on September 13 will be one of the legend's "best".

The 34-year-old became sole possessor of all the title belts at the weight for a second time when he beat IBF champion William Scull by unanimous points decision in Riyadh last month.

Crawford was at that bout and immediately threw down the gauntlet -- gladly accepted by Alvarez -- even though it means the 37-year-old American has to step up two weight divisions.

Alvarez, whose record is an impressive 63-2-2 with 39 knockouts, has been a world champion at four different weights, as indeed has Crawford.

"This fight is going to be one of my best fights in my history, in my record," Canelo said at a joint press conference with Crawford in Riyadh to get the promotional show on the road.
