Celtic Supporter Liason Officer has offered up an explanation as to why the letter regarding use of Season cards was sent out to fans.

Some fans were left disgruntled yesterday when the letter dropped through their door letting them know they cannot transfer their season cards to a friend or family member in the event they could not make the game.

So, the letter was intended to offer clarity on the use of ST's we've recently seen a few examples of season books being used incorrectly, leading to problems for supporters on a match days, it was designed to avoid further problems, apologies for any confusion/upset casued

The letter was seen as pointless to the majority of fans who will continue to use their card in the way they always have.

As we suspected it was more to do with adults skipping in as concessions and not concerning the vast majority who got the letter.
