Ash Taylor had quite a lot of games where he had a complete nightmare, off the top of my head are,

ICT away 1-3 when he gave away a pen and was at fault for the other 2 goals.

Maribor home 1-1 he was at fault for the goal.

St Johnstone away 0-3 on a Friday night a few seasons back he was horrendous that night.

Dundee United home 0-3 His debut when he set up a Dundee Utd player for one of their goals it might have even been GMS.

Im sure there were a lot more that I have erased from my memory, the point is if he was playing on Saturday instead of Arnason or AOC we would have probably still lost 3-0 because he was shyte and wasn't good enough.
