Why are we so sure that we'll be mid-table?
On paper, this is the strongest squad we've had in a decade. We have a decent mix of true talent, along with experience and some grit. Wenger was able to eke out a lot more out of truly horrible teams in the past. At the very least, they seemed to buy into his philosophy and gave it all on the pitch. We weren't great, but we didn't constantly get beaten 3-1, 5-1, etc. We were getting to CL quarter finals, and even a semi-final back then, too.
He's definitely not getting the most out of this lot.
This teams needs Major surgery and with all the uncertainty around our manager and not being in the champions league I can't see us having a good 2017/2018 season..
By my reckoning this is what we need.
New left back..
New centre half..
New right back to push Bellerin
New holding midfielder
New striker to replace Sanchez
New number 10 to replace Ozil.
Factor all this with a board that have no clue about football or appointing a new manager I'm worried.
Also Tottenham, Liverpool and even Manchester United are no longer teams we can laugh at. They have now surpassed us.
We already don't spend big on players so without champions league I wouldn't hold your breath on getting suitable replacements.
