Rules were introduced last season to prevent players and coaches from gambling on any football activity worldwide.

At this stage, the FA are only investigating an internet betting exchange, but if Colback is found to have bet on the game, even though it was a European fixture, he will be formally charged with an offence and is likely to face a heavy fine.

Although some will argue the new rules are too strict, the FA decided it was better to ban all betting activity in order to make it clear to footballers they should not be tempted to gamble on a sport they have a vested interest in, as well as potential inside knowledge.
