Arsenal supporters are not impressed with Alex Iwobi after he slapped Matteo Guendouzi on the training ground.
Video footage shows the moment midfielder Iwobi lands a savage slap on the back of the Frenchman’s head.
The sound of the connection makes a large thud and the 19-year-old is sent rocking forward.
He then turns around to give his team-mate a stern warning.
Some Arsenal fans found it hilarious.
“Hahaha Iwobi absolutely clocked him around the head,” one stated.
Another added: “That slap on Guendouzi tickled me.”
But others did not take it so lightly.
“Jesus Christ he absolutely battered him with that,” a third suggested.
And a fourth even claimed: “Iwobi almost knocked Guendouzi out there.”
The Gunners have enjoyed recent success in the Premier League, winning their last three games.
But they have not been tested in Europe yet and Emery has admitted he wants them back in the Champions League as soon as possible.
