Arsenal hosts PSG on Tuesday in the first leg of their Champions League semifinal at the Emirates. The Gunners return to this stage for the first time since 2009 after knocking out defending champions Real Madrid with a 5-1 aggregate win. PSG took down Liverpool and Aston Villa to reach their fourth semifinal in five years.

The Gunners beat PSG 2-0 in the league phase of the Champions League way back at the start of October and it was fairly comfortable for them, although PSG did hit the woodwork twice and showed glimpses of the team they have become.
