Szczęsny was dismissed for upending Arjen Robben and denying the winger a goalscoring opportunity in the 37th minute, as the Gunners were eventually beaten by second-half goals from Toni Kroos and Thomas Müller goals.

Was it Robben? Was it the referee? Was it the fourth official? Did Arsène Wenger know?
"I did not see it," he replied.
