Obinna told journalists in Calabar that it was just a tip of what to expect from him at the London Olympics as he is now back in his full strides.
The 10.11secs time recorded by Metu is his personal best.
“I am speechless, many things have been said about me but I thank God I have proved them wrong today. My training in Jamaica and Atlanta is paying off already” he said.
“Though this is my personal best, I believe I can still run 9 seconds, I will remain focus and continue to work harder” he assured.
Last year’s champion Ogho-Oghene Egwero finished second in a time of 10.19 Stanley while US based Stanley Azie 10.32seconds.
National athletics coach, Innocent Egbunike, who was highly impressed, said after the race that Metu’s victory was a result of hard work and focus.
“There are times he would nearly pass out during training session but he remained focus and kept working harder. I am not surprised he won here today,” Coach Egbunike said.
Dethroned champion, Egwero said he was not moved by his defeat as he knows within him that he will surprise all at a bigger stage. He said the race was not a difficult one and that he would bounce back.
The 100m champion, Metu, has also qualified for the finals of the 200m event and looks good to complete a double on Thursday.
