The 30-year-old was a regular for Paderborn in the Bundesliga last season, having previously only played lower league football, and also received international recognition from Albania in the past year.
He is known for his protective helmet, which he has worn since a cheekbone injury in 2013, and his penchant for yellow cards, breaking the all-time Bundesliga record in 17 bookings last season.
He is the first HSV signing since Daniel Thioune was appointed as head coach, but their second signing of the summer following Amadou Onana, whose move from Hoffenheim was confirmed earlier in the year.
He will likely act as a replacement in defensive midfield for Adrian Fein, who is not expected to come back after a loan from Bayern Munich.
“We are very happy to have Klaus, an experienced player, on our team,” said sporting director Michael Mutzel. “He should strengthen our defence as an important stabiliser, but in addition to his defensive qualities as a two-footed player, he also has a flexible game structure.”
“I played with Paderborn here last season at the Volksparkstadion and had the atmosphere made a lasting impression on me,” said Gjasula himself. “When the call came from Hamburg, I didn’t have to think long.”
Paderborn had confirmed Gjasula’s departure from the club on Tuesday after two years, having failed to agree a new contact. “It will be a nice challenge for him and I wish him the best of luck for it,” coach Steffen Baumgart told the Westfalen-Blatt before his destination was made known.
