In six weight classes - 48, 54, 60, 69, 81 +91kg - boxers will compete for a place in the last eight today at the XV AIBA World Championships in Milan. And at stake are not only the the quarter-final places, but also the immaculate record of the so far unbeaten Cubans.

Olympic silver medallist and World Cup winners Yankiel Leon Alarcon and Carlos Banteur Suarez will take on Razvan Andreiana of Romania at light-flyweight and Mikael Zewski of Canada welterweight respectively, lightweight Idel Torriente finds himself up against Husnu Kocebas of the Netherlands while hitman Jose Larduet Gomez is pitted against Revaz Karelishvili of Georgia at light-heavyweight, one of the most interesting divisions in the entire tournament. All four Cubans are in action in Ring A this afternoon.

Russia - another boxing powerhouse, has suffered some unexpected casualties so far. They will be represented by light-heavyweight Artur Beterbiev and super-heavyweight Denis Sergeev on Monday afternoon. An exciting performance will be expected from Brian Castano of Argentina at welterweight. The youngster from Buenos Aires has so far disposed of an Australian and a Lithuanian in his first two matches, causing something of a sensation.

Having benefitted from the three-week training camp in Assisi prior to the World Championships, Botswana light-flyweight Bathusi Mogajane has made it to the last 16 and is hoping to proceed against top seed Lukasz Maszczyk of Poland in the first bout of the afternoon.
