(Arsenal vs Olypiakos) What went wrong???

30-9-2015 East-Asia  (2.45am)  

Oxlade-Chamberlain sat on the floor rued of what could have and should have after a poor display, a rather shocked and disbelief reactions from the home fans after Arsenal have lost to Greek champions Olympiakos by the scoreline 3-2. In a match full defenders mistakes and plenty of wonder moments from the forwards decided that Olypiakos were the final winners. Post-match, when asked about the match by the media, Wenger simply considered it as a match lacked of luck. However, there is plenty more to consider despite the fact that Arsenal were dominated the match in overall, this isn't all just about luck.

To make it clearer and makes sense, various players mistakes will be highlighted:

1)  Many have blamed on the Arsenal's shot stopper David Ospina for failed to catch a seemingly easy corner ball and let it slotted home as a decisive winner for Olympiakos. Perhaps Petr Cech was a better keeper after all, but every keeper made mistakes right?

Ospina lost his touch and allowed Olympiakos to make it 2-1

2) Mesut Özil has created some remarkable chances in the game, he made some beautiful passes that was wasted by the perhaps a bit of selfish Sanchez, and one of them is a free kick that was saved by the Olympiakos' goalie.

Özil curls the ball perfectly onto the right corner just to be denied by Gago.

However, he made some mistakes too throughout the game. 

Özil involved himself in a rather unnecessary fight with Olympiakos' player,
saw him given a yellow by the Dutch referee

Perhaps most spectators didn't see what was actually happened when Olympiakos scored their first goal, many thought that it was merely a deflected own goal by Walcott. In fact, it was more than that, Özil was actually responsible for the first goal. When the Olypiakos player delivered the corner ball to the outside of the box, Özil was the closest to the scorer, he should have seen it coming and intercepted it.

3) Before the match, Wenger knew that they can't afford to loss another match in the Champions League. Perhaps to much surprise, he laid out a rather controversial starting-11 to replaced Monreal with Gibbs and to play David Ospina instead of Petr Cech. To be fair, Wenger was under pressure to rotate his squad because everyone on the cold bench was hunger to prove their value, Wenger knows he can't just leave them there the whole time. One best example that best describe this situation is Mathieu Flamini's wonderful display against Tottenham that saw him slaughtered them 2-1, that shows everyone in the squad can be play at the highest level. Unfortunately, it works the opposite way and Wenger has screwed it up.

Mathieu Flamini was fantastic in the match against Tottenham.

Chemistry between Gibbs and Sanchez didn't turn up well in the horrible night, maybe Gibbs has gotten a bit of rusty after a long time on the bench

Why chose Gibbs when Wenger knew it's not the best match for warming up.
