Arsenal beat Western Sydney Wanderers 3-1 on Saturday, giving them an 100% success rate so far in pre-season.

Other than the fact that Arsenal are looking pretty sharp at front having scored five goals in two games, albeit against A-League teams, what else did we learn from the Gunners’ win over WSW?

5. Mohamed Elneny can play at centre-back

Who would have thunk it? Elneny was pretty excellent at centre-back against WSW and even scored a goal. Fine, it took a wicked deflection, but the 25-year-old almost scored a worldie in the second half and was generally brilliant.

Something tells me this won’t be the last time we see Elneny in this position.

4. Alexandre Lacazette’s got moves

Although the newbie didn’t score this time, Lacazette displayed his fantastic movement, which is explains why Arsene Wenger wanted to sign him so badly.

The boss likes forward who can score, assist, and help with build-up play, which Lacazette can do.

3. Arsenal need to keep Olivier Giroud

Giroud scored Arsenal’s first goal, demonstrating once again why the Gunners should be trying to keep hold of him this summer.

At the moment, it seems as if the big guy could be leaving, which would be such a shame.

2. Emi Martinez needs to be taught how to football

What the hell was he doing when he picked up Aaron Ramsey’s backpass? Surely that’s goalkeeping 101?

1. Ox is half man/half tank

Seriously. There aren’t many footballers out there that are as muscular as him.
