The 29-year-old handed in a transfer request at Stamford Bridge after falling out of favour under ex-Blues boss André Villas-Boas.
And the former PSV Eindhoven defender signed a three-year deal with PSG in January, linking up with his former Chelsea manager Carlo Ancelotti in the French capital.
“I feel better at PSG than I did at Chelsea,” Alex was quoted as saying in the Daily Star. “Chelsea’s squad had a lot of big names – and that entails a lot of egoism.
“Nobody at PSG feels more important than the others. We’re at the start of a big adventure and we’re all pulling in the same direction.”
Alex joined Chelsea from Santos in 2004 and was loaned to PSV Eindhoven from 2004 to 2007 before returning to the Premier League, winning the FA Cup in 2009 before completing the double in 2010.
And the defender believes the French league is more competitive than ever, with no sides dominating the division.
“The French first division is a very defensive-minded and difficult league,” he added.
“It is often tougher than in England, where certain teams feel beaten before the start when they play Manchester United or Chelsea.
“It will be tough, but if France continue to defend well, they have a real chance of beating England.”
