The German club signed the French midfielder on loan from Arsenal on the final day of the transfer window for the rest of the season.
Arsenal tried to offload the 21-year-old throughout the window after he fell out with Mikel Arteta, but he had to wait to seal a move to Hertha Berlin.
Guendouzi has been on international duty with the France Under-21s and will only have a few days of training under his belt with the Hertha Berlin squad ahead of their clash against Stuttgart on Saturday.
Sporting director Michael Preetz admits that Guendouzi will need time to adapt but conceded that the process needs to be accelerated as the club cannot afford to see him take too much time.
He indicated that Guendouzi’s quality on the ball and his ability to act as the conduit between the defence and the attack will come in handy for Hertha Berlin this season.
“We have to give him time to adapt”, Preetz told German magazine Kicker.
“But we don’t have that much time.
“We need to accelerate the process.
“He is very safe on the ball and always wants the ball.
“He is a hinge between the defence and the offence.”
Guendouzi recently insisted that he has unfinished business at Arsenal but he will enter the final year of his contract with the Gunners next summer.
