Bayern's press and Kane's movement can create a heavy workload for Arsenal's back line. Arsenal's first-pass structure and compact cover offer a way to escape that pressure and reach the space behind Bayern. Real Madrid can create chances through Vinícius, Mbappé and set pieces against Leipzig's outer cover. Leipzig have their own receiving and transition routes, but their away finishing supply has been thinner than their home scores suggest.
Bayern's high recovery can feed Kane and Díaz, yet Olise is suspended, Musiala is out and Kimmich remains a doubt in the current pre-match picture. Arsenal have repeatedly limited clean chances, including in the direct meeting with Bayern, and Gabriel with Konsa recently handled Saliba's absence. Rice and Ødegaard can move the first forward pass toward Saka rather than feed Bayern the loose exits Leipzig gave them. Arsenal's cover and their own wide reception should keep this match balanced. That's why I'm siding with Arsenal.
Madrid can test Leipzig's right side through Vinícius before moving to Mbappé and Bellingham. Leipzig's Banzuzi and El Aynaoui can release Nusa, Gruda or Nkunku, but the team's recent away games at Bayern, Como and Leverkusen supplied fewer finished chances than its home games. Madrid's recent large scores included an unusual cluster of late corner contacts and a penalty; Vinícius changes the left-side combination used against Sevilla, and the right-side setup is still unsettled. A controlled Madrid spell can produce chances without the match repeatedly turning into end-to-end finishes. That's why I'm siding with fewer goals in Real Madrid against Leipzig.
