Kingston (Jamaica), May 28 (IANS/CMC): World 100 metres champion Yohan Blake says his main goal this season is to win three gold medals at the World Championships in Moscow August 10-18.

The double Olympic sprint silver medallist and second-fastest man ever in both the 100m and 200m says his goal includes retaining his world title.

"My big goal this year is to retain my title at the World Championships and to win three gold medals there,” Blake told Swedish media outlet SVTplay.se Monday.

“I have told myself that this year I am going to be an alien because I want to invade; I want to take over the world."

Blake capitalised on a Usain Bolt disqualification in the final of the 100m at the last instalment of the World Championships in Daegu, South Korea, winning the gold medal ahead of Walter Dix of the US and veteran Kittitian Kim Collins.

The 23-year-old went on to post a personal best 19.26 in the 200m.

He enjoyed a stellar 2012 after beating Bolt twice at the national trials, before picking up silver medals in the 100m and 200m at the London Olympics and running the third leg on Jamaica's record-smashing 4x100m relay team.

"When I retain my title and become a world champion for the second time, I think that will be a good season," said Blake.

Only two others have managed to win successive 100m gold medals at the World Championships.

American Carl Lewis won three consecutive titles in 1983 (Helsinki), 1987 (Rome) and 1991 (Tokyo), while his compatriot Maurice Greene also boasts a three-peat with wins in 1997 (Athens), 1999 (Seville) and 2001 (Edmonton).

"I can be more than historic because I know what I can do,” the Jamaican sprinter declared.

“I have been training really hard and I know what I can do."
