SEBASTIAN Larsson’s agent has hit out at Blues, claiming they have treated the winger like a farmer would cattle.

And Per Jonsson suggested that Blues should ‘shape up and get a little bit of class’.

Blues told Larsson that they would now NOT consider his sale in the January transfer window - and were preparing another new contract offer.

Blues decision came after they rejected a transfer request from Larsson on Thursday, a fact confirmed by Jonsson, and rebuffed Blackburn Rovers.

Blues had previously accepted a £1 million offer from Newcastle United. It was believed no personal terms could be agreed, but Jonsson stated there were still ongoing talks with Newcastle as late as Wednesday.

Rovers’ £500,000 plus bid was rejected, and then Blues decided they wanted to keep the Swedish star until the season’s end regardless.

That has brought an angry response from Jonsson, who spoke to the Birmingham Mail to put his and his client’s case.

"It has been a funny six months since the new owners have come in," he said.

"When Seb reported back for pre-season he was told that the club wanted to sell him. They asked me to find another club and employed other agents to sell the boy. They wanted £4 million for him.

"We accepted that, then, in mid-August, suddenly Seb was told ‘no, we are not going to sell you, instead we want to discuss a new contract’. We were surprised and we negotiated for a month and by the end of September we had basically agreed a deal with Julia Shelton [Blues head of football administration].

"She said everything was fine and she needed to go back to the board to get confirmation.

"We heard nothing for two months and in mid-December were told communication with Hong Kong was very difficult and suddenly a completely new offer was made which was lower than the one we had verbally agreed.

"Now, we are aware a verbal agreement isn’t binding, a written agreement is what’s needed.

"But there were substantial differences in the new offer, three years plus a two-year option loaded to Birmingham’s advantage, and the salary was lower. Naturally, we turned it down.

"Negotiations finished and it was said that, to be clear, the manager wanted to keep Seb for the whole of the remaining season, that he was an important part of the team. The manager told Seb this himself.

"Out of the blue, this month, we got an email saying Birmingham had accepted an offer from Newcastle for Seb.

"This quickly got out in the media, which sparked more interested from other suitors and the speculation in regard to Seb started to grow rapidly.

"So we had been talks with Newcastle up to Wednesday and then the plug was pulled yet again, and Birmingham decided they wanted to keep him.
