The Frenchman was visibly displeased on more than one occasion during the game, particularly during the incident that saw midfielder Alex Song receive a second booking and the amount of stoppage time that was added.
Song was sent off after 55 minutes, as he received a second yellow for obstructing play. The north London club's manager has since expressed his displeasure at the decisions that led to the player heading for an early shower, while branding both yellow card incidents as "harsh".
The former Monaco boss has also appeared to be unhappy with the amount of time added on after the regular 90 minutes, which proved to be decisive as striker Darren Bent scored the leveller during the 95th minute.
Following the game, it appeared as though Wenger placed his hands on the fourth official, Martin Atkinson, as the Daily Mail now claims that the manager could be sanctioned by the FA.
A victory at the Stadium of Light would have sent Arsenal to the top of the table, albeit on a temporary basis until the completion of Sunday's fixtures.
