He was constantly questioned about the contracts of Arsenal's key players-how the club had allowed Alexis Sanchez, Mesut Ozil and Alex Oxlade-Chamberlain's contracts to run down withut trying to renew them.
Liverpool will pay a fee of £35m for Oxlade-Chamberlain - the same figure that was previously agreed with Chelsea for the versatile midfielder.
A number of Arsenal players have taken to Twitter to send messages to Oxlade-Chamberlain following the England international's move to Liverpool on transfer deadline day. It has been a massive help.
"Since the last game I have been waiting and hoping we could make this transfer - and when I got the news he was ours it was fantastic".
"But I can't wait to get to Melwood and you'll hear first from me on LFCTV".
City remain very keen to sign Sanchez from before Deadline Day ends, though, and will improve on that initial offer.
For the midfielder to turn his back on both that money and that promise is a damning verdict on Wenger, who clearly failed to make the most of one of England's most talented players.
"He may still be young but he has a lot of experience in the Premier League, Champions League and for his country. I welcome him to the Liverpool family".
Teams aren't built around wing-backs, though, and Oxlade-Chamberlain thinks he can find a more prominent role in central midfield at Anfield.
He will become Liverpool's second most expensive signing after Guinea global Naby Keita, who will join the club from next season after the Reds triggered a £48m release clause in the RB Leipzig midfielder's contract.
