Luhukay surprised to win race for Kalou
Ivory Coast international Kalou sealed a move to the Bundesliga on Sunday after being linked with several other clubs.
The 29-year-old joined Hertha for an undisclosed fee, reported to be €3million, and Luhukay believes his new recruit will prove to be a shrewd acquisition.
"He has extra qualities, is an exceptional player.” Hertha coach Luhukay told Bild.
"He has played for years [in the] Champions League. There is already surprising that we had a chance with him and he has chosen for us.
"Kalou has all the qualities you can have.
"He is a player who has mobility, has unpredictability, has speed, goalscoring, also a good heading ability."
Kalou is away on international duty and the former Chelsea man could make his debut in the Bundesliga clash with Mainz next Saturday.
