BRUSSELS (Reuters) ¿ Asafa Powell (pictured) believes he can break his 100-metre world record for the second time in less than a week but only if race officials at today's Golden League meeting in Brussels do their job properly.

The Jamaican sprinter ¿ who lowered his own 100 metres world record to 9.74 seconds in Italy on Sunday ¿ blamed the starting official at last year's Van Damme meeting for denying him the chance to set a new record.

After a slow start he won the race in 9.99 seconds.

"I know I can run faster than 9.74, because I sprinted at only about 90 percent. I just also hope the starter doesn't give me problems like last year," Powell told reporters ahead of today's event.

Organisers in Brussels had hoped to pit Powell and American world sprint champion Tyson Gay against each other but Gay, who won gold medals in the 100 metres, 200 and 4x100 relay at the world championships in Osaka, has decided to skip the meeting.

Despite the disappointment of not seeing a Powell-Gay showdown, the 47,000 sell-out crowd can still expect some excitement in the first of two Golden League meetings in three days. European athletics' elite series moves to Berlin on Sunday.

Two athletes ¿ US 400 metre runner Sanya Richards and Russian pole vaulter Jelena Isinbajeva ¿ remain in contention for a share of this season's lucrative jackpot prize.
