SV Hamburg Sunday signed Brazilian playmaker Thiago Neves for a club record fee of more than 9 million euros (13.2 million dollars).
The 23-year-old midfielder was officially presented Sunday after signing a five-year deal.
It brings Hamburg's spending on new players this summer to around 28 million euros, more than any team in the Bundesliga, the dpa reported.
Thiago Neves has chosen the German Bundesliga club despite the interest of Atletico Madrid and then offer of an improved pay deal from Fluminense.
"It wasn't a question of money because Fluminense offered me more than than Hamburg, but it is a challenge for me," he said.
The transfer follows the signings by Hamburg during the week of left-back Marcell Jansen from Bayern Munich and central defender Alex Silva from Sao Paulo.
Jansen made his debut in Hamburg's 4-2 victory at Arminia Bielefeld on Saturday.
Earlier this month Hamburg also signed Croatia striker Mladen Petric from Borussia Dortmund.
Hamburg had earned money from the sales of midfielder Rafael van der Vaart to Real Madrid for around 16 million euros and defender Vincent Kompany to Manchester City for a reported 8 million euros.
