Arsenal goalkeeper Wojech Szczesny could face punishment over an obscene gesture made during his side's 2-0 defeat to Bayern Munich.
The stopper had a torrid night as he was sent off for a foul on Arjen Robben, conceding a penalty in the process. As he left the pitch, Szczesny made the gesture, before heading down the tunnel.
Few in the stadium, including his manager Arsene Wenger picked up on this, however the whole incident was picked up by television cameras.
UEFA will now investigate to seen whether the action is worth punishment. The Polish keeper is already banned for one match after his red card yesterday, which could be extended should he be found guilty.
This isn't the first time one of Arsenal's players have landed themselves in hot water for an inappropriate gesture. Jack Wilshere was charged for raising his middle finger to Mancherster City fans late last year.
Luis Suarez was also banned by the Football association in 2011, after putting his middle-finger up at Fulham fans during Liverpool's 1-0 loss at Craven Cottage.
However, players such as Wayne Rooney and Ashley Cole have escaped punishment over such offences in recent years.
