Arsenal pulverised FC Basel in the UEFA Champions League in Switzerland, with Lucas Perez scoring a hat-trick in a 4-1 victory in Group A on Tuesday night.
The north London giants won the group as Paris Saint-Germain failed to beat Ludogorets in the French capital.
Lucas gave the Gunners the early lead after only seven minutes, and he grabbed his second strike minutes later, as Alexis Sanchez linked with Keiran Gibbs for both efforts.
The attacker completed his hat-trick at the start of the second half, and Alex Iwobi added his name to the scoresheet as Sanchez and Mesut Ozil pulled the strings.
