Wengers future could easily be decided as well - if this was my club, I would be so seriously worried:
Petr Cech - turns 36 in 4 months
Laurent Koscielny - 32 - looks to be in decline
Nacho Monreal - turns 32 next month
Per Mertesacker - 33 - looks too slow
Hector Bellerin - 23 - the only real talent in defense, how long will he stay ?
Alexis Sanchez - 29 - out of contract and on his way out of the club
Mesut Özil - 29 - probably the same as Sanchez
Oliver Giroud - 31 - will leave in the summer
Theo Walcott - soon 29 - on his way out of the club
Santi Cazorla - 33 - career over ?
Danny Welbeck - 27 - yet to reach 50 League goals. Scored 13 in 3.5 seasons for Arsenal. Not good enough
Mohamed Elneny - 25 - hardly ever plays - not good enough
Calum Chambers - 23 - hardly played after his first season at the club. Not good enough
Realistically - 10-12 players could easily leave Arsenal in the next 1.5 years. Either because they want to leave, or because they aren't good enough
Yep, they are fecked. About to lose the only two world-class players they have, and probably going to get a combined £30m for the both of them at this rate which doesn't even get you a Danny Drinkwater these days.
Furthermore, their best prospects are the likes of Alex Iwobi, Reiss Nelson and Ainsley Maitland-Niles, sorry but not a patch on some of the players the other top sides have coming through and I wouldn't expect any of these guys to be anything special.
They're incredibly reliant now on a player that spends 80% of his time in the physio room as well and is also out of contract at the end of the season currently. Ramsey is another who's out of contract soon (2019), who's caught between probably not being good enough as a starter but being a great squad player, but he's on £100k+ a week already.
They arguably need over the next few windows:
- New long-term GK
- Another RB for depth/competition.
- A new commanding CB + maybe 1 more for depth (Mertesacker retiring, Chambers not good enough, Koscielny ageing).
- Proper DM
- New CM playmaker (depending on Wilshere/Cazorla futures I guess).
- New AM to replace Ozil
- 3 new wide-forwards (needed a RW anyway, replace Sanchez, greater depth).
- Another ST
Probably the best vaguely realistic scenario for their starting XI next season IMO is something like:
--------------Lacazette----------------
-----------------------------------------
Lemar-------Mkhitaryan-------Malcom
-----------------------------------------
-------Wilshere-----N'Zonzi------------
------------------------------------------
Kolasinac--Koscielny--De Vrij--Bellerin
------------------------------------------
-------------------Cech------------------
