Arsene Wenger is hoping that Arsenal can win their home games in order to progress from their Champions League group.

Putting in a terrible display in Croatia, the Gunners imploded in the first half when Olivier Giroud got himself sent off for being stupid and the Ox found the back of his own net.

They then went two goals down in the second half and game themselves a mountain to climb.

Despite bringing on three subs all at the same time; a rare action for the boss, Arsenal were only able to claw one goal back and became the first English side to lose to Dinamo Zagreb.

Arsene Wenger also became the first manager to lose 50 games in the competition (though how many have managed enough to lose that many in the first place?)

Speaking to the press after the shambles in Croatia, the boss said  “We have enough games to come back. We focus to win our next home game and I’m sure we can beat Zagreb at home.”

Before their next Champions League game, however, Arsenal have the small matter of a trip to Stamford Bridge followed by one to White Hart Lane.

They need to get themselves together quickly if this week isn’t going to go from bad to worse to downright unbearable.
