Antoine Griezmann admitted that he needs more time playing with Luis Suarez and Lionel Messi to unlock their capabilities in attack.

"It's my second month since I arrived, I have to get used to it and play more with them to understand the movements of Suarez and Leo," said Griezmann following a 0-0 draw against Dortmund in the Champions League.

Marc-Andre ter Stegen made a penalty save on Marco Reus to preserve the tie.

"Marc is a world-class keeper. My penalty was not really well-taken. Back to the training ground for that," said Reus.
