FC Basel will host Arsenal on Tuesday in UEFA Champions League group stage play.
Arsenal has already qualified for the knockout stage of the Champions League, along with PSG. But PSG will win the group if it beats Ludogorets on Tuesday, no matter what Arsenal does against Basel.
The good news for Arsenal is that several top teams—including Real Madrid, Bayern Munich and Porto—are also currently in second place, meaning that the Gunners would avoid them in the round of 16.
The Gunners are coming off a 5–1 win over West Ham on Saturday. Basel fell 3–1 to Young Boys this past weekend.
