Alex admits he's desperate to quit Chelsea in January.
The Brazil defender told The Sun: "I know it's not the best time to go in January, in the middle of the season. But I have to think about other things, I have to think about my own interests.
"I tried to leave before this season started but when (Luiz Felipe) Scolari arrived they did not want to let me go. I had already spoken to the club before he came. Now that the transfer window will open again in January I will try again. I think this time it will happen."
Alex insisted he was not trying to cause boss Scolari more worry than he has already.
After all, with just one win in their last five home games and nothing to spend in January, losing a player is the last thing on his mind.
Alex explained his desire to play regularly to make it back into the Brazil team is his reason for wanting to leave.
He said: "It's a difficult situation for me. I have nothing against the manager but he has two great defenders in Terry and Carvalho. I have nothing against the guys who are playing - they are always very good.
"Chelsea have one of the best defences in the world. Terry and Carvalho are doing very well. They don't make many mistakes and have been playing together for four years."
