Sir Alex Ferguson was described as "too distraught" to face the media in the wake of the defeat, with assistant Mike Phelan taking his place.
But Uefa have come out publicly in support of Cakir, and Ferdinand could be handed a ban for the gesture if the referee or match delegate reference the incident in their reports of the game.

Only last month, Luis Suarez was cautioned in the dying minutes of Liverpool's Premier League clash with West Brom for applauding Jon Moss after the referee awarded the Baggies a free-kick.
In September 2005, Wayne Rooney was handed a two-match ban for clapping and swearing at official Kim Milton Nielson during a Champions League encounter between United and Villarreal.
