PSV Eindhoven defender Alex claims Chelsea are attempting to secure a work permit in order to bring him to the Premiership.
The Brazil international was loaned out to the Dutch side immediately after he was purchased by the Blues in 2004 from Santos due to perceived difficulties in obtaining a permit.
But after two seasons in the Eredivisie, the 24-year-old centre-half claims Chelsea are upping their efforts to secure the necessary paperwork so that he can finally play in England.
"The chance that I will leave PSV is quite big," Alex told Dutch newspaper De Telegraaf.
"At this moment Chelsea are very busy with getting a work permit for me.
"Earlier they did the same with Salomon Kalou and several other players, which worked out fine."
However, the powerful defender has warned Chelsea boss Jose Mourinho that he won't be happy with a permanent place on the substitute's bench.
Alex earned the plaudits after leading PSV to a surprise Champions League last 16 victory over Arsenal and is looking to establish himself in the first team at Stamford Bridge.
"Chelsea are a great club, but it is most important that I will play a lot of games there," he added.
"If I only sit on the bench, it will be difficult. But whether that will happen, you only know when you are there."
