Hamburg are set to complete the signing of Brazil defender Alex Silva from Sao Paulo later this week.
Hamburg sporting director Dietmar Beiersdorfer and team doctor Oliver Dierk have travelled to Brazil to sort out details of the transfer.
Jorn Wolf, spokesman for the Bundesliga club, told their official website, www.hsv.de: 'It is right that sporting director Dietmar Beiersdorfer has flown to Brazil in order to clarify the last details with the player Alex Silva and the selling club Sao Paulo.
'Our team doctor Dr Oliver Dierk has accompanied him in order to carry out our medical obligations. He will examine the player on the spot.'
Hamburg are keen to bring in a replacement for Vincent Kompany, who moved to Premier League side Manchester City last week.
And the club views the 23-year-old Silva, who has won eight caps for Brazil, as an ideal signing.
Wolf added: 'When the examinations and the last details with Sao Paulo are sorted, we expect all three back in Hamburg by the middle of the week. The exact time frame is still not certain though.'
Wolf revealed Hamburg could also make further signings as they look to strengthen their squad for an assault on the Bundesliga title.
'The board and the coach (Martin Jol) made clear after the departure of Vincent Kompany that the transfer fee should be invested straight back into strengthening the team,' he said.
'It is to be assumed that this week yet more transfers will be negotiated.'
A creative midfielder - to fill the gap left by Rafael van der Vaart's departure to Real Madrid - appears to be high on Jol's list of priorities.
'As the coach has already made clear, the club is also looking at the creative area in midfield,' Wolf added.
