Leverkusen should have long spells of the ball and seek early wide entries. Marseille can meet that with a high regain and a quick route into the space behind the first home attack. The size of any lead depends on whether Leverkusen end the next Marseille possession and turn their own volume into another clean finish.
García and Maza can feed Schick, while Marseille have Gouiri, Paixão and Weah to move the ball forward after a regain. Leverkusen's recent home defending gave Stuttgart second contacts and late space; Hoffenheim also limited their accurate shooting. Harit scored in Marseille's last match but Genesio has ruled him out, and Emerson is also absent, so the available Gouiri and wide runners matter more. Schick, Maza and Moreira all played Leverkusen's last match, keeping the home threat clear. Marseille's current pressing and finishing routes give them a credible reply even if Leverkusen control the ball, so I'm siding with Marseille to stay close in regular time.
