Player Ratings v City
By Young Hans Solo
November 5 2017

Quoted before the game: "the best way to beat City is to attack" So Wenger picked five defenders.

Cech - 5 couple of great saves but should have done better on the first goal.
Kolasinac - 4 when he's strong he can't he beat. Lazy on first goal and generally poor often.
Coquelin - 4 wrong position
Kos - 3 useless
Bellerin- 3 invisible
Monreal - 4 useless
Ramsey - 4 ran about a bit had one good chance
Sanchez -4 poor looked like he's already gone
Ozil - 4 back to being invisible
Iwobi - 4 tried but it's not his level
Xhaka - 4 out of his depth

Subs
Lacazette - 6 took his chance well and looked lovely immediately
Wilshire - 6 not on long but far more comfortable on the ball
Giroud -5 not on long but no service

Wenger - 0 cost us the game before it started . Team were not prepared and looked lazy. Then picked the stupidest side.
