Peter Odemwingie has accused West Bromwich Albion of 'stealing' his loyalty and says he should have handed in a transfer request 12 months ago.
The Nigerian striker wants to leave The Hawthorns before the window closes after being the subject of a failed bid from Queens Park Rangers, but saw a transfer request rejected on Friday.
He subsequently released a statement expressing his disappointment at the decision and has now fired off a second outburst on Twitter.
Odemwingie is thrilled to have captured the interest of Rangers boss Harry Redknapp and tweeted on Saturday night: "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 percent. the rest they stole out of my pocket thinking I was keeping money in there."
Odemwingie earlier on Saturday came under fire from some Albion fans after making clear his desire to leave.
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.
"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."
Adkins was relieved of his managerial duties nine days ago after taking the club to back-to-back promotions and 15th place in the Premier League, with his dismissal arriving two days after a 2-2 draw at Chelsea.
He was immediately replaced by Argentinean Mauricio Pochettino, with the general consensus being that Adkins had been harshly treated.
The Southampton fans certainly felt so and sang their former manager's name during the 0-0 draw with Everton last Monday, but Cortese stands by the move he made.
In an interview with Sky Sports News, he said: "Nigel and I, we always had a very good relationship, to the last second. It was very tough, not just for him but for me.
"To me, there's one time, which is right, especially if you are 100% convinced it is the right thing. Ultimately for the team it was the right thing, it was perfect timing
"It sounds harsh but it was for the benefit of the progress we want to achieve over the next couple of months and years. It's not only for today but for tomorrow."
Cortese has attracted criticism in the wake of the sacking, with Saints icon Matt Le Tissier accusing him of having an ego problem.
According to Cortese, though, everything he does is for the benefit of Southampton.
He added: "Maybe I need to sacrifice my popularity to get the right decision. If that's the case, I'm happy.
"I am a perfectionist. Some people say that's not good, but it helps the football club to keep attention to detail and not stand still."
On Le Tissier, a one-club man afforded hero status by the Saints fans, he said: "I don't even know him, he's never met me. Anyone in the past who is associated with the club is stirring negativity towards me should probably ask if it's beneficial for the club. I would not allow myself to judge someone I have never met."
On the future of the club, but as a whole and with Le Tissier, Cortese asked everyone to get behind his vision.
He said: "I'd like in the future, for the supporters to buy more into what we do as a club. Not players, managers or chairmen, the club.
"I am not excluding anyone. Anyone who has Southampton at heart has a place."
