Olivier Giroud scored his 100th goal for Arsenal as the Gunners beat BATE Borisov 4-2 to go two-for-two in Europa League group play on Thursday.
Arsenal rested nine front-line players including Alexis Sanchez, Mesut Ozil and Alexandre Lacazette for the English Premier League and still had enough firepower at a venue usually hostile to visitors. Within 25 minutes, Arsenal was a decisive 3-0 up through two goals by Theo Walcott and Rob Holding.
Giroud sent the goalkeeper the wrong way from the spot in the second half.
"Welcome to the 100 club!" tweeted Walcott, who has scored 107 for Arsenal.

Lazio won a second straight Group K game after beating Zulte Waregem 2-0, while Marseille lost at Salzburg 1-0.
In Borisov, Jack Wilshere broke down the left and provided a perfect cross for Walcott to net from close range in the ninth minute, just a minute after he hit the post.
BATE goalkeeper Denis Scherbitski blundered in the 22nd when his clearance found Walcott at the edge of the area to score his second with a low shot.
Just three minutes later, Holding scored his first goal for Arsenal following a corner kick.
Ivanic reduced the deficit for the hosts with a header, Giroud restored the three-goal margin, and Gordeichuk finished off the scoring.
