Barton was involved in an altercation with Gervinho, which resulted in the Ivorian forward being red-carded for ‘slapping’.
Speaking on Twitter after the incident, Barton said: “I went down easy, no doubt. Still cant raise ur hands (sic)”.
The ‘slap’ came in retaliation to Barton dragging Gervinho up from the ground after a perceived dive.
“I think @joey7barton was in the wrong today! He should not have got involved and assaulted Gerviniho like that,” Wilshere commented.
When Barton objected to the charge of assault, Wilshere opined: “That is a form of assault my friend it should not happen on a football pitch!”
Saturday’s match ended in a goalless draw.
