The dynamic winger found the net once while contributing two more assists. Both sides presented very strong starting elevens in the final showing before next weekend’s Premier League start.
Arsenal had no hesitation to find the back of the net Saturday afternoon in Helsinki when Welsh international Aaron Ramsey made a neat pass to Walcott, who found space behind the defense and beat keeper Joe Hart in the ninth minute.
The Gunners were able to hold the lead going into halftime before making a host of substitutions, including the introduction of top preseason goal scorer Olivier Giroud.
Manchester City were unable to contain the north London side and were exposed twice in a five minute span to go down by three.
Walcott set up the next two opportunities with expert precision, putting Ramsey and then Giroud away, both of whom were able to beat the City keeper.
The Etihad side were able to get one consolation goal when forward Alvaro Negredo fought Laurent Koscielny off the ball to beat the Arsenal keeper.
Although the match took on the label of friendly neither side treated the match as such by opting to start their high profile players.
The Gunners saw a lineup consisting of players who all have Premier League experience while the Citizens did the same, including new boys Negredo and Fernandinho.
