If you want to give Antonio Rudiger the benefit of the doubt, call it a clumsy challenge.
Taking that benefit to the extreme, you could say Ilkay Gundogan ran into the stiff arm of an immovable force. Either way, Gundogan - after half an hour of goalless Manchester City dominance - came out of the collision significantly worse and his team-mates were far from happy.
Perhaps those team-mates had flashbacks to the collision between Rudiger, then at Chelsea, and Kevin de Bruyne in the 2021 Champions League final which left the Belgian with a broken nose and fractured eye socket.
