Brazil's World Cup hope Neymar has confirmed he is moving to Spanish champions Barcelona on a five-year contract.
The gifted 21-year-old striker chose Barcelona on Saturday over their Spanish arch-rivals Real Madrid after Santos ended three years of resisting offers for Neymar and let him go before next year's tournament in Brazil.
"On Monday I'm signing a contract with Barcelona," Neymar said on his Instagram page and Twitter account.
"I want to thank the Santos fans for nine incredible years."
Neymar has been a first-team regular for Santos for the past four years, scoring 156 goals and providing 77 assists in 256 matches.
He guided them in 2011 to their first Copa Libertadores triumph since when Pele represented the club in the 1960s, and he has already established himself at international level, scoring 20 times in 32 appearances with Brazil.
'In my heart'
Neymar said that his feelings for the club and the fans would never change.
"Titles, goals, dribbles, celebrations and the songs the fans created for me will always be in my heart," Neymar said.
"This is a different moment for me, sad (departure) and happy (new challenge). God bless me in my choices.
"I made a point of playing tomorrow's match in Brasilia. I want the opportunity to enter the pitch once more with the 'mantle' (Santos shirt) and hear the fans shout my name."
Santos play Flamengo at the capital's refurbished World Cup stadium in their opening match of the Brazilian championship on Sunday.
The club said on Friday they had agreed to transfer Neymar and let him choose between two offers.
Folha de Sao Paulo newspaper put the latest offer from Barcelona at 74 million Brazilian Real ($36.12 million).
Barcelona said that Neymar stood out for his polished skills.
"He makes a difference and scores goals," the club said on their website.
"He has received many accolades and the praise of the celebrated Pele, of whom he is considered his heir".
The reigning South American Player of the Year will link up at Barcelona with Argentine ace Lionel Messi, four times FIFA World Player of the Year.
The pair faced each other when Barcelona beat Santos 4-0 in the Club World Cup final in December 2011.
Barcelona are looking to revamp their stellar squad after what by their high standards is a slump during which they have been eliminated from the European Champions League at the semi-final stage for the past two seasons.
Lining up Messi and Neymar together will likely keep the Barcelona standard at least as high as in their Champions League and Club World Cup winning seasons, a benchmark arch-rivals Real Madrid could struggle to match.
Neymar has been a target of top European sides for at least three years, including Chelsea in 2010, but Santos managed to reject all offers and improve his deal with sponsorships.
The ready smiling Neymar became a celebrity, had a part in a television soap opera and admirers imitated his Mohican style haircut.
However, since the middle of last year a move had become increasingly difficult for Neymar to resist while Santos lost the form that took them to their third South American Libertadores Cup title in 2011 and first since Pele's 1960s heyday.
"After rejecting a series of million-dollar offers for Neymar Jr, since the middle of 2010... against the trend in Brazilian football of selling its best talents quickly, Santos FC finally agreed on negotiations," Santos said on their Facebook page.
"Santos FC is freeing Neymar Jr, knowing they made all the efforts to keep him in Brazil for as long as possible."
