"A coach the country is praising now will one day be sacked and to his achievements they will say: only one cup? I beg." Odemwingie tweeted.
"Too much corruption in sports these days. Because of few sportsmen who cheat now doping control went from urine to blood test."
Interestingly, Osaze had a public row with Keshi just before the Nations Cup in South Africa when the coach sensationally axed him from the Eagles.
Osaze also said his commitment to his club affected his relationship with former Eagles coach Samson Siasia.
"Very little thing made me fall out with ex-Eagles coach Siasia, and that's club commitment. And that commitment was questioned after," Odemwingie tweeted.
"What did that teach me? You only a good guy and professional when you score and give your teams what they want. They throw us out after."
He added: "When I give all my heart and effort to a team and get overlooked after, how could I possibly be happy? Same in Eagles. Same in WBA. "Well praised and most criticised at the same time. Something is wrong somewhere. And I bet it’s not in my attitude. I believe in transparency."
