Arsenal continued their imperious start to this Champions League campaign, with a 3-0 win over Slavia Prague.
The Gunners arrived in the Czech Republic, having won their first three fixtures without conceding a single goal.
They took the lead in the first half, thanks to a controversial penalty converted by Bukayo Saka.
After the break, Mikel Merino scored a brace to secure another victory for Mikel Arteta’s men.
Luis Diaz scored twice for Bayern Munich against Paris Saint-Germain, before he was sent off at the Parc des Princes in an eventual first half.
Although PSG pulled one back through Joao Neves, the Bundesliga champions held on for all three points, as they maintained their perfect start.
