CRAIG GORDON
The pressure on the former Hearts keeper has been upped considerably by the arrival of Dorus de Vries.
Competition for places is essential in football but when it comes to goalkeeping the pressure is taken to a different level.
On the back of a couple of wobbly performances Gordon now faces the biggest challenge of his Celtic career, de Vries is clearly a favourite of the manager but if Gordon performs to his best the Dutchman will need to bide his time.
