Manchester United, Newcastle and Celtic face a crucial week in the Champions League as they look to keep their hopes of reaching the knockout stages alive.
But Arsenal will book their spot in the last 16 if they avoid defeat against Lens on Wednesday - and could even qualify before kick-off if Sevilla beat PSV Eindhoven in the earlier kick-off.
Holders Manchester City have already qualified alongside RB Leipzig, Bayern Munich, Inter Milan, Real Madrid and Real Sociedad.
The top two teams in each of the eight groups advance to the knockouts, with third place dropping into the Europa League.
