Dwain Chambers produced a stunning display to win the 60m final in the fastest time this year at the indoor World Trials and UK Championships.
Chambers, 31, confirmed his prospects as a World Indoor gold medal contender with a time of 6.50 seconds.
Harry Aikines-Aryeetey finshed second with a personal best of 6.55secs with Craig Pickering in third in Sheffield.
Chambers, who won silver at the World Indoors in 2008 in Valencia, is now ranked number one in the world.
â€œItâ€™s nice but itâ€™s still early days, Iâ€™m sure the Americans are going to come out and do something crazy,â€ said Chambers, who served a two-year suspension for taking performance-enhancing substances, after his victory.
â€œItâ€™s nice to know I have made the team and can hopefully focus my attention towards Doha now.â€ Chambers will be joined by Aikines-Aryeetey, 21, in the Great Britain and Northern Ireland team for next monthâ€™s World Indoor Championships in Doha, Bahrain.
â€œIâ€™m just happy that Iâ€™m realising my potential and things are moving in the right direction,â€ said the Londoner.Olympic relay gold medallist Mark Lewis-Francis finished fourth in a time of 6.67 secs
