"It does go through your mind that you might have to go elsewhere," said Miller. "It wasn't looking too rosy for me at the start of the season. I didn't even get off the bench in the first game against Kilmarnock, so it wasn't looking great. Even though I got the goals on Sunday, I can't be sure of playing for Celtic next week.

"At the moment, the club have six strikers and that's maybe one or two too many. I want to know I'm part of the plans, one of the four first-choice strikers the manager will maybe rotate. Beyond that, I want to get a starting position.

"I never imagined I would be playing against Falkirk last week, so I was shocked to hear my name in the starting line-up. Getting the goal was obviously a bonus for me, but it's even more important that I'm making a contribution and helping the team win.

"As a striker, it is important to get off to a good start in a season. Last year, I obviously didn't get off to a good start and it more or less continued that way throughout the whole season. So to get three goals in my first two games is great for me personally and hopefully I can continue that way.

"When you go on a run of scoring goals and get that kind of momentum, things do happen more naturally for you. If you are not scoring, you tend to think about it a lot more. You need the breaks as well. Last season, a couple of those goals I have scored already this season might have hit a defender's legs and been blocked."
