I'm also playing as Arsenal. Playing my second game now. I finished my first season and wasn't really feeling it. I overpaid for some players (Fellaini and Adrian) so I decided to start again and it's been much enjoyable since.
Tactics:
4-2-3-1 (GK, LB, RB, CB, CB, CM, CM, AML, AMR, AMC, ST)
4-3-3 (GK, LB, RB, CB, CB, DMC, CM, CM, AML, AMR, ST)
3-6-1 (GK, CB, CB, CB, LWB, RWB, DMC, AMC, AMLC, AMRC, ST)
Transfers:
Out:
Chamakh - Lille 3m
Arshavin - Juventus 4m
Squillaci - Valencia 500k
Pohjanpalo, Gregoritsch and youths all loaned out for first team action.
In:
Joel Pohjanpalo - HJK 200k (one of my favourites - couldn't get Demirci who I like also).
Michael Gregoritsch - Hoffenheim 2.9m (only young - to replace Giroud if he isn't performing after 2-3 seasons).
Moussa Sissoko - Toulouse FC 14m (my favourite Vieira replacement - Diaby is too injury prone in the game).
Stevan Jovetic - AFC Fiorentina 12.5m (first was listed for 25m then when he got injured it dropped and signed him on deadline day).
Main 11:
------------------ Szczesny ------------------------
--Sagna -- Koscielny -- Vermaelen (c) -- Gibbs--
------------- Sissoko ------ Arteta -----------------
--Walcott ---------- Cazorla ------------ Podolski--
-------------------- Jovetic --------------------------
Bench / rotation:
Mannone
Mertersacker
Jenkinson
Santos
Wilshere
Ramsey
Chamberlain
Gervinho
Giroud
Always injured:
Diaby :'(
Ignore/don't like:
Fabianski
Djourou
Rosicky (I actually like them all but game time is vital for youngsters and lots of players always coming back from injury too).
All who will be leaving at the end of the season. Chamberlain to inherit #7. Ramsey to inherit #8 when Arteta gets too old or retires. I'd also like to try save my money to buy back Cesc Fabregas and convert Wilshere into a winger like when he was in the youth sides. I know he has the #10 but I'd like to eventually make the perfect 4-3-3 with Ramsey, Fabregas and Sissoko just bossing the show and Wilshere, Walcott and Jovetic finishing teams for fun. Already got big plans for Chuba Akpom as well as Serge Gnabry. Trying to sign Luke Shaw is difficult but I sense I will have more luck in the second season along with a better backup keeper (I always fail at finding the right balance of back up keeper and someone who's good so I stick with what I have... I ain't paying 7m for Butland who in 2 season will complain that he isn't playing first team).
Apologies about the lack of screen shots -- I prefer to type **** out as they get all a bit same-same.
FM is my life ^^)
