Following the 2-1 loss to Dinamo Zagreb in the opening Champions League group stage clash, Arsenal couldn't really afford to lose again, with Bayern Munich on the horizon.
However, the Emirates Stadium left disappointed on Tuesday night, as Greek side Olympiakos came to North London and left with all three points in a shock victory.
Felipe Pardo had put Olympiakos in front, only for Theo Walcott to pull Arsenal level moments later. Arsenal's torrid night was summed up by an own goal from goalkeeper David Ospina, and even though Alexis Sanchez equalised again, Alfred Finnbogason won the game for Olympiakos just past the hour mark.
On a night of negatives for Arsenal, one positive came out of the game. Walcott's performances as a striker continue to improve, having been largely used as a winger during his time under Arsene Wenger.
The England international has now scored six goals in his last seven games, whilst he also notched an assist for Sanchez's goal against Olympiakos in an influential display up front.
Now, former Gunners star Liam Brady has told talkSPORT that he was impressed with Walcott's performance against Olympiakos, and claims Arsenal don't have any problems in attack as a result.
"We don’t have a problem in the forward area, not as much as people like to make out," said Brady. "Theo will play. He scored again and did really well for Sanchez’s goal," he added.
Arsenal fans have long wanted a new striker to come in and replace Olivier Giroud, and given that Danny Welbeck has struggled to justify his move from Manchester United, the emergence of Walcott as a striker this season is a welcome boost for Wenger.
Walcott needs to continue his recent performances, but it looks like the 26-year-old could be the man to solve Arsenal's recent striking problems after an impressive run of goalscoring form.
