The balls for use in the Champions League final at Wembley Stadium on May 28 have gone on display.
The ball has a distinctive star design and Samir Nasri of Arsenal, one of those on hand to talk about the ball, was happy as it was in the red and white colours of his club.
Nasri's Arsenal are still in the hunt for the final. They play away to Barcelona in the second leg of their round of 16 match on Tuesday.
Arsenal won the opening leg 2-1 and Nasri says his team will go on the offensive:
"We come to attack so they let space to us and we have players who have plenty of pace and we have a good opportunity to win. They are the favourites but we can beat them," he said.
Salomon Kalou of Chelsea was also at the reception. His team already leads Copenhagen 2-0 and will be playing at home on March 16.
"I think we did the best job there by winning 2-0 and now we have to confirm by playing at home in front of our fans and prepare the second leg," said Kalou.
Nasri sportingly said he hoped for an Arsenal versus Chelsea final as that would be wonderful for the fans. Kalou said he agreed, because Chelsea has a really good record at beating Arsenal.
