Antoine Griezmann has said he needs time to gel with Lionel Messi and Luis Suarez, after Barcelona escaped with a point against Borussia Dortmund in their Champions League opener on Tuesday.
Barcelona held on for a 0-0 draw away to the Bundesliga side in their Group F clash, after goalkeeper Marc-Andre ter Stegen saved a second-half penalty from Marco Reus.
Messi made his first appearance of the season, after recovering from a calf injury, coming on as a second-half substitute.
But it was a frustrating night for the Spanish champions, whose side included Suarez and recent arrival Griezmann.
"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.
"We have not knocked on the door enough and we must improve and work at it. It is a point but Marc stopped a penalty and made other saves," Griezmann told Movistar.
