Arsenal have benefited from a UEFA rule for their crunch Champions League tie against Bayer Leverkusen.
Arsenal, who are leading the way in the Premier League, won each of their eight Champions League league phase fixture, topping the standings to reach the next round.

The Gunners head to Germany having won four games in a row, including booking their place in the FA Cup quarter-finals following their 2-1 victory over Mansfield Town on Saturday.
Ahead of lining up against Leverkusen, Mikel Arteta has been given a boost as he will be able to call upon the services of Piero Hincapie despite being on loan from the German outfit.
Hincapie joined Arsenal from Leverkusen on a season-long loan last summer, with an option to make it a permanent deal at the end of the season for £45 million.

Hincapie has been an important player under Arteta, having played 27 games across all competitions, including four Champions League appearances.
The Ecuadorian's versatility has proved to be crucial since signing for the club and he is in line to feature against Leverkusen after making an appearance off the bench against Mansfield.
