PSV Eindhoven have revealed that they made an attempt to sign Chelsea's Brazilian defender Alex on loan.
Alex is reportedly unsettled at Stamford Bridge, but the Dutch side have confirmed that the Blues rejected their approach for the 26-year-old.
"We contacted Chelsea, but the answer was clear. They don't want to let him go under any circumstances," PSV director Jan Reker told Dutch newspaper De Telegraaf.
Chelsea allowed Alex to spend three years on loan at PSV before utilising their buy-out clause for the player in 2007.
Alex reportedly told The Sun earlier this week: "I told Chelsea a few days ago that I wanted to leave. There are many options, but I have to think them through and see if Chelsea will let me leave in January."
However, the Blues responded by issuing a statement which read: "Chelsea would like to make it clear that no transfer request has been received from any player.
"Chelsea will decide the future of any contracted player in the best interests of the club."
Alex has made 51 appearances since arriving at Stamford Bridge in the summer of 2007 and is currently enjoying a run in the side with Ricardo Carvalho sidelined due to injury.
