The German side's CM made fun of Cech's skills in an effort to praise former shot-stopper Bernd Leno, who was benched in favor of the Czech goalie.

Community managers working for football clubs have to be careful when trying to make jokes about other team's players, because they might be forced to issue an apology.

Such was the case of Bayer Leverkusen's CM, who tried to make fun of Petr Cech's ball-handling skills during the game between Arsenal and Manchester City. The German side's accounts mocked Cech mainly because the Czech goalie was chosen over former Leverkusen shot-stopper Bernd Leno, and they believed that a joke would go unnoticed.

Then, Leverkusen's CM took it a step further by posting a video of Bernd Leno playing the ball out from the back without any problem.

As you could have expected, Petr Cech didn't enjoy being mocked and tweeted against the German side, questioning their values and true sportsmanship.

In the end, Bayer Leverkusen's account replied, offering an apology to the Czech goalkeeper.
