Whittaker has no Rangers regrets
The 23-year-old enjoyed a dream start at his new club following his £2million move from Hibernian in August.
He told Rangers News: "I know that I am not in the starting 11 right now but it is a long season and we have a very big squad so I think there will be a lot of changes in the months ahead.
"Players will be rested at times and others brought in so it is just a matter of taking your chance when it comes along and impressing the manager.
"At a big club that is the way it should be and I am confident the group of lads we have can have a successful season."
