The trolley dash was to fill many places in the starting 11. We only need one WC striker this time. Everything else is a nice to have
The trolly dash was after we got hammered 8-2 by United. If it wasn't for that Wenger would have gone into the season with a squad he thought was good enough for whatever his ambitions was.
Last season he bought a keeper thinking his squad is good enough to win the league. This season is probably going to be the toughest ever. (Some team is probably going to win the league with 20 points now

)
Chelsea revived under under new management.
United under Mourinho whom he's never beaten in the league + some signings the could improve their squad.
City with doing what City does + Pep.
Spurs is active and we only manage to pass them on the last day.
Leicester seems to be keeping their squad intack.
Liverpool first full season under Klopp.
Wenger is going into the season with the same, somehow expecting a different outcome. He's probably going to be forced to bring his international players back early, which will have us neck deep in bandages again by October.
He hasn't done enough in the transfer market for 10 years, he always comes up just short. He'll never win the league with tactics, the only why he can and the only way he has won the league is by having the best team. Tactically he comes up short against everyone I've mentioned above.
I am just tired watching the same movie over and over. Sorry for the negativity, just how I feel at this moment. Tomorrow we'll sign Messi as our tax accountant and all will be well again.
