Odemwingie has followed up the statement he issued on Friday night with two separate outbursts on Twitter, claiming he wants to leave because the Baggies had previously doubted his commitment.
QPR have already had a £2 million bid for the Nigeria international turned down but sources close to West Brom expect them to make another offer.
Odemwingie is thrilled to have captured the interest of Rangers boss Harry Redknapp and tweeted: "Best compliment I have ever received in my (career) as a player. manager like HR spending to bring me for mission "impossible"."
He also wrote: "Offer came, everybody knows.
"I ask club what they think ? Answer - not now. Maybe summer. I ask- or is it tactics to get more money? Answer- we have enough now there is no prise (price) for you. We need you.
"I say ok. What's the prise for summer ? We will tell you after the window closes.
"I say - I have served the club well and deserve at least to have a prise now so I can plan my probably last move in England.
"Don't want another summer window not knowing what will happen cos now I ll have to move my little son elsewhere. after all I have contributed to the clubs success last two seasons I hoped to at least get a low prise. Answer- talk later.
"Last season January window is when I should have handed in transfer request. Was one foot in Rubin Kazan - not for sale. Fulham. Not for sale. Newcastle. Not for sale. Wigan. Not for sale.
"Loyalty left 70 per cent. the rest they stole out of my pocket thinking I was keeping money in there."
