"Hertha will see Klinsmann benefit in January" - Grujic

Klinsmann was appointed to Hertha's supervisory board last month, before stepping into the dugout when Ante Covic left the club following the Old Lady's 4-0 loss at Augsburg on Matchday 12, their fourth defeat on the bounce and fifth game in a row without a win.

Klinsmann, who has previously coached Germany, Bayern Munich and the USA, has overseen a narrow 2-1 loss to title aspirants Borussia Dortmund and the 2-2 draw at Eintracht Frankfurt and Grujic - who scored in the latter - thinks the best is yet to come.

"I think we'll see benefits from January, benefits [from] working under Jürgen Klinsmann, because this is such a short time." He explained to bundesliga.com at the Commerzbank Arena. "This is only nine, 10 days together so we have to keep working. The staff is really amazing!"

Klinsmann's all-star cast includes former Werder Bremen coach Alexander Nouri as his assistant and Germany legend Andreas Köpke as his goalkeeper coach. Liverpool manager Jürgen Klopp can rest assured the young Serbian is in safe hands.

Klinsmann, back in a Bundesliga dugout for the first time in more than a decade, is happy to be back in the mix and optimistic a first three-point haul - against Freiburg next Saturday - lies in wait.

"The players enjoyed it," he said. "I think they feel that something is growing together. It'll take some time. This is not happening overnight. Maybe we've slid down in [this or] that area because things didn't work out the way we wanted, but now I can see there's a good spirit there and we'll look forward for next week."
