Odemwingie has followed up the statement he issued on Friday night by claiming he wants to leave because the Baggies had previously doubted his commitment. The Nigeria international is a target for QPR and on Friday had a transfer request rejected by Albion.
Rangers have already had a £2 million bid turned down but sources close to West Brom expect them to make another offer before the transfer window closes on Thursday. He tweeted: "I can understand the reaction of few Albion fans on my desire to leave the club. Real reason? Cos they once doubted my commitment."
He went on: "Want to know why I wanted to quit top flight football last summer earlier than I wished to? They know at the club. Albion fans are not the only reason, but made it easier for me to decide to stay and try my best to forget about the disappointment.
"I succeeded in doing that. But it's not getting better.Before bigger disappointment comes one day, I better leave on a good note."
Odemwingie admits his agent advised him not to make the Twitter outburst. He added: "I am crazy haha adviser text saying don't tweet, it weakens our position. Doesn't weaken nothing ! When I want to do something, I Do it."
In his original statement, released after his transfer request being rejected, Odemwingie said: "I'm deeply hurt and in some ways offended by the lack of reciprocal common respect from the management of West Bromwich Albion.
"During my time at the club I believe I have delivered performances, effort and goals. I never complained when I found out that the club failed to inform me of enquiries that might have interested me and my family in the past.
"Everyone knows how much effort and commitment I always give when I play for the club. The fans have been great with me and I will always respect them.
"At this stage of my career, this opportunity may not come around again. A new challenge, a new opportunity, and a chance to play under the stewardship of one of the most respected managers in the game (Harry Redknapp)."
