United States international attacker Wood will join the Bundesliga club following the tournament.
The 23-year-old signed from second-tier side Union Berlin before leaving Germany for the Copa America Centario in the United States.
He has started three games at the tournament, scoring in the 4-0 defeat of Costa Rica last week.
Speaking to Bild, Labbadia said: "I have the feeling that he has just taken another next step in his development."
Earlier this year, United States head coach Jurgen Klinsmann backed Wood to make a move to the German top flight, and Labbadia added: "The feedback I receive is good."
