New Gunners boss Unai Emery opted to keep the £56 million signing on the bench as he preferred Pierre-Emerick Aubameyang to lead the line in a 4-2-3-1 formation for the North Londoners against defending champions Manchester City.
With Cech preferred to former Leverkusen stopper Bernd Leno, who left the German club to join the Gunners in the summer, they replied to a clip of a mistake with "we know a guy." before running a video of Leno playing out from the back. "They have different qualities but for us in the way we want to play, they can [both] play". Leno is now on the fringes of the German National Team and certainly could be a starter for Die Mannschaft.
Witty users also hit back at the Bayer official account highlighting a mistake by Leno when he was playing for Leverkusen after completely missing the ball from a back pass that subsequently resulted in an own goal.
Cech, now 36-years old and in his 15th Premier League season, has certainly proved himself enough to keep hold of the starting spot for the near future.
City are much more talented than Arsenal right now; they are much better organized right now and, for that, we shouldn't put too much weight on the first game of the season. 'Petr Cech can continue to start the match.
Speaking to reporters (via BBC Sport), Emery said that there is more to come from the young midfielder.
For me it's very important he stays with us.
The 36-year-old survived a heart-stopping moment in the first half when he nearly scored an own-goal, leading some to ask why summer signing Bernd Leno didn't start between the sticks.
Ahead of his Premier League debut, Emery spoke to the press and we picked up three key takeaways from his comments.
That being said, Emery said he understands that players may be slow to adjust to a new philosophy and style of play. I want a consistency in our way.
"It's the wrong time in the first game of the season, against Manchester City, the best team in the league".
However, Lehmann said he was "surprised" that Cech tried to play out from the back so often against City.
