-LRB- CNN -RRB- -- Brazilian playmaker Kaka was officially presented as a Real Madrid player , after being handed the number eight jersey in front of thousands of supporters and a huge media contingent at the club 's Bernabeu stadium on Tuesday evening . Kaka parades his new Real Madrid jersey after completing his $ 92 million transfer to the Spanish giants . An estimated 50,000-strong crowd , almost three times the anticipated number , turned up to watch the ceremony as Kaka was unveiled as Madrid 's latest addition by club president Florentino Perez and honorary president Alfredo di Stefano . Latest transfer gossip and rumors Kaka , who completed his medical earlier in the day having landed in the Spanish capital in the morning , has penned a six-year contract and has cost Madrid a reported $ 92 million . There had been speculation that Kaka would be handed the number five shirt that Zinedine Zidane had once worn for Madrid , but the new arrival will instead take up the number eight shirt formerly worn by Fernando Gago . The presentation took place on a stage erected on the Bernabeu pitch that also included Madrid 's record nine European Cup trophies , a giant screen and with a backdrop of four huge images showing club legends Raul , Juanito , Di Stefano and Zidane . The 27-year-old Kaka , who was named player of the tournament after helping Brazil win the Confederations Cup in South Africa over the last few weeks , told supporters : `` Today is a very happy day for me . `` I 'm very happy because this new stage of my career will be at Real Madrid . I hope to write my name into the history of this club with many victories and successes . '' Kaka was the first signing confirmed by Madrid after Perez returned to the club presidency at the start of June . Soon after bringing in the Brazilian , Perez also agreed a world-record 80 million euros fee with Manchester United for Cristiano Ronaldo . That deal was finalized on Friday night and will come into effect from Wednesday , with Ronaldo , who like Kaka will be tied to the Spanish giants until 2015 , being presented on July 6 . Aside from Kaka and Ronaldo , Madrid also struck a deal to sign Valencia defender Raul Albiol last week for a fee believed to be around 13 million euros , while the likes of Franck Ribery , David Villa and Xabi Alonso are all being linked with moves to the Bernabeu as Perez relaunches the famous ` galacticos ' policy that he presided over during his first tenure at the club . Then , while president from 2000-06 , Perez sanctioned the big-money signings of superstars such as Zidane , David Beckham , Luis Figo and Ronaldo , a policy that reaped indifferent rewards with Madrid winning seven trophies under Perez in total but none in his final three years .
