Arsenal remain unbeaten in the Premier League this season, but it was yet another draw for the Gunners this weekend. Arsene Wenger will have been hoping for better than their 2-2 and 1-1 draws with Everton and Leicester City respectively, but it wasn't to be after an entertaining encounter against Manchester City on Saturday.
Sergio Aguero put City ahead, but superb goals from Jack Wilshere and Alexis Sanchez gave Arsenal a second half lead. Arsenal couldn't hang on for the three points though, as a late header from Martin Demichelis gave City a share of the spoils in North London.
Arsenal went with a 4-1-4-1 system again, with Mathieu Flamini in holding midfield with Mesut Ozil, Jack Wilshere, Aaron Ramsey and Alexis Sanchez supporting Danny Welbeck. It's a slight modification on the usual 4-2-3-1 system used by Wenger in recent years, but it's been far from perfect so far.
The biggest issue to date has been the continued poor performances of Mesut Ozil. The £42.5m signing was always a No. 10 for Germany and Real Madrid, and was last year for Arsenal too, but now he's been played out on the left hand side - which really hasn't worked. Confining Ozil to one side of the pitch restricts him from roaming into space and creating behind a striker, whilst he also doesn't offer enough defensively to cope with overlapping full backs - as we saw against Everton with Seamus Coleman's goal.
Over the years, Wenger has shown that he can be adaptable. His all-conquering Invincibles side was done using a 4-4-2, and he's been using the aforementioned 4-2-3-1 system for some years before switching to 4-1-4-1 - and now he may need to change it again.
Ozil needs to be played as a No. 10, and limiting their record signing seems a peculiar decision from Wenger. Instead. the Frenchman should at least consider changing to more of a diamond in midfield in order to get the best out of a number of his players.
The general shape of most of the team stays the same, with a back four, Flamini in holding midfield with Aaron Ramsey and Jack Wilshere slightly further forward. The difference comes in the usage of Ozil, Sanchez and Welbeck in attack.
The system to the right has been used to great effect recently by Chile, Roma and even England in their recent win over Switzerland - and it suits some Arsenal players perfectly.
Ozil flourished at Real Madrid when he had speed ahead of him in Cristiano Ronaldo and Angel Di Maria, and he could now have that in Sanchez and Welbeck. By putting him in the attacking midfield role, Ozil has the license to roam and create with more space being created by the pace of Sanchez and Welbeck pushing defences back.
Meanwhile, Sanchez and Welbeck would occupy more "wide forward" roles - which they have both played at international level with Chile and England respectively - the latter had his best game for his country in that role against Switzerland last Monday with two goals. With the license to spread out and play wider, Arsenal wouldn't necessarily lose much of their width either.
The roles could also be Santi Cazorla behind the two forwards, whilst Lukas Podolski and Joel Campbell are also good fits to play as "wide forwards", and whilst it's unlikely that Wenger would switch to play this untested formation, the roles best suit some of Arsenal's talent - which is currently being shoehorned into the 4-1-4-1 formation with only moderate success.
