Blues confirm Alex offer
Chelsea have received an offer from a rival Barclays Premier League club for defender Alex, manager Andre Villas-Boas has confirmed.
Reports have claimed the bidders are west London rivals QPR, whose new manager Mark Hughes has indicated his interest in the Brazilian.
Villas-Boas said: "From what I know from my chief executive, there has been an approach from a Premier League club."
He added: "It is a player who we have accepted a transfer request for, so we have to listen to offers."
Chelsea are planning to replace Alex with Bolton's Gary Cahill, who they have struggled to agree personal terms with.
Villas-Boas insisted he had set no deadline for a deal to be concluded and but was hopeful that would happen before the end of the week.
"Still an ongoing negotiation, not that we don't want it resolved as soon as possible," said Villas-Boas, who refused to criticise Cahill or his representatives over the player's wage demands.
"I'm sure that all of the parties are protecting their interests."
Villas-Boas denied that Chelsea had made a reported £25million bid for Lille star Eden Hazard but admitted he was a fan of the player.
