Brazilian defender Alex has been presented as a Paris Saint-Germain player in the French capital after completing his move from Chelsea.

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 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 5 million euros (£4.18m).

Alex said: "I had a problem with the coach, he doesn't like my football. I preferred to leave for another club."

The Brazil international had been the subject of interest from QPR but has chosen 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.

Qatar-backed PSG, who spent more than 80 million euros last summer, have yet to buy a major striker, having failed to sign Alexandre Pato from AC Milan and Carlos Tevez from Manchester City.

Ancelotti is unconcerned, however, as PSG are not involved in the Champions League.

"When you play the Champions League you need four strikers. But to play the league and the Cup, (Kevin) Gameiro and (Guillaume) Hoarau are enough," the former Chelsea manager said.
