The North End boss is one victory away from a quadruple of elevations on his CV at this level having already lifted Blackpool, Leeds and Huddersfield into the second tier during previous managerial stints.
The Lilywhites, who are currently on an 18-match unbeaten run in the division, are one point ahead of third-placed MK Dons heading into their final clash away at Colchester.
Given the high stakes, Grayson could be forgiven for feeling some anxiety, particularly with North End’s dire record in the play-offs, but he insists his belief in the current crop at Deepdale remains too strong to allow any nerves to creep in.
“I’m not nervous at all,” he declared. “I’ve got a lot of trust and faith in my players. There have been some darker days than the build up to this game over the season.
“When you’ve got an opportunity that’s in your hands and have a group of players who are really focused, working hard, who are full of confidence off the back of an 18-match unbeaten run – I’ve got a lot of faith in them that they can go out and finish the job off.”
