BERLIN, Aug 31 (Reuters) - Hamburg SV have completed the signing of Argentina World Cup captain Juan Pablo Sorin from Villarreal, while also tying up a deal to take Serbia striker Danijel Ljuboja on a loan deal from VfB Stuttgart.
Sorin, 30, was presented to the media on Thursday after signing a three-year contract with the Bundesliga club.
'This is an emblematic signing for the whole Bundesliga,' Hamburg coach Thomas Doll told reporters. 'Hamburg have brought in the captain of the Argentina national team.'
Hamburg have paid a reported 2.5 million euros ($3.21 million) for the defender, who said he was delighted with the move.
'Hamburg are a big club,' he said. 'I've always found the Bundesliga interesting. Good football is played here.'
Hamburg have had to remodel their defence after selling centre backs Daniel van Buyten and Khalid Boulahrouz to, respectively, Bayern Munich and Chelsea.
Dutchman Joris Mathijsen and Belgium's Vincent Kompany have come in to compensate and the arrival of Sorin will give Hamburg a further boost as they look to make progress in the Champions League and challenge for the Bundesliga title.
Doll's side will play Arsenal, Porto and CSKA Moscow in Group G of the Champions League.
Stuttgart confirmed on Thursday that Ljuboja would be moving to Hamburg on a one-year loan deal.
Ljuboja, part of the Serbia & Montenegro World Cup squad, scored eight goals for Stuttgart last season.
