Chelsea defender Alex has been presented as a Paris St Germain player in the French capital this afternoon to indicate his move from Chelsea is complete.

PSG sporting director Leonardo joined Alex in addressing the media in a press conference broadcast live by PSG TV.

The 29-year-old joined Chelsea in 2004 but has struggled for first-team football under Andre Villas-Boas this season and has now been reunited with former Blues boss Carlo Ancelotti.

French sports newspaper L'Equipe reported that the transfer fee was £4.18 million.

The Brazil international had attracted interest from QPR but chose to move to the big-spending Ligue 1 side.

"He will be a PSG player. It was a good opportunity given his price and his desire to join PSG," Ancelotti told an news conference earlier in the day.

Alex, 29, joined Chelsea from Santos in 2004. He was loaned to PSV Eindhoven from 2004 to 2007.

He leaves Stamford Bridge having made 86 Premier League appearances for the Blues.

"He has a lot of experience because he played in the Dutch and English leagues and also with his national team," added Ancelotti, who took over from Antoine Kombouare as PSG coach last month.

"He is a great professional. I think he will have a good season."

Alex is PSG's second major signing during the January transfer window after fullback Maxwell joined from Barcelona.
