The Scotland skipper is well used to sides putting up the barricades now.
Fletcher said: "I'm sure Rangers can take a lot of positives from this draw. It will give them great confidence to go forward.
"With Scotland we faced Liechtenstein and this was almost like playing them again given the number of men Rangers had behind the ball and how tough it was to break them down.
"But that's part of football and something you have to expect.
"If a team is organised and well drilled then you can find it tough."
