Tuesday's Champions League football - LIVE!

"Arsenal fans have expressed their disappointment at Arsene Wenger's decision to field David Ospina in goal instead of a fully fit Petr Cech. The line-up includes Alexis Sanchez playing upfront despite the experiment failing to work in Arsenal's first two games of the season, while Alex Iwobi's inclusion in the team may pay off and stretch PSG's defence - even if he's only just returned from injury. For PSG, the major surprise is that Lucas is on the bench while Thiago Motta and the returning Javier Pastore also make up a strong set of substitutes."
