Stefan Savic is suspended for Atletico, and that should see Jose Gimenez come into the starting XI. Diego Simeone has no other injury issues, but could bring Thomas Lemar into the side after he scored the match winner off the bench against Espanyol. Agustin Marchesin and Marko Grujic are both ruled out for FC Porto, with Diego Costa expected to deputise for the former. Zaidu Sanusi hasn't started a game since early August and recently saw a deadline day exit blocked by the club. Ivan Mercano may therefore continue at left-back for the visitors. Toni Martinez received his marching orders against Sporting after coming on as a sub, but is available.
