Birmingham City manager Steve Bruce has criticised the club's board over the decision to sell Matthew Upson to West Ham United.
The Blues accepted a £6million bid for the England defender late on transfer deadline day and Upson was given permission to speak to the Premiership club.
The fee could eventually rise to £7.5million, but Bruce has revealed his unhappiness at the sale with City attempting to secure promotion back to the Premiership.
"I'm disappointed with what's happened. I think we've made the wrong decision. But, that's my opinion. They're (the board) going to see things differently," he told Sky Sports News.
"I'm paid to get on with my job and I will do, as best I possibly can.
"There are a lot of clubs in our division that have kept hold of their star assets.
"I wanted to do that too. I wanted to say to him 'Look Matt, listen I understand what you want to do, but in my opinion it wasn't quite right'."
