Celtic have been fined £21,000 by UEFA after the club's fans displayed an offensive banner during their Europa League encounter with Udinese in December.

The charge related to "the displaying of an offensive banner and setting off of fireworks by fans" during the tie in Italy.

The banner displayed during the match reportedly criticised European football's governing body.

The Scottish club were found to have breached article 11 of UEFA's disciplinary regulations in relation to "the use of gestures, words, objects, or any other means to transmit any message that is not fit for a sports event, in particular if it is of political, offensive or provocative nature".

Celtic currently sit top of the Scottish Premier League.
