Given their dominance north of the border, both Rangers and Celtic serve a purpose when it comes to the progression of footballers who ply their trade in the United Kingdom. If you are a player competing anywhere in the world but you require experience before a move to the English Premier League, Glasgow is usually the place to go. If you are a player on the cusp of first-team football at a top club in Europe, the Old Firm giants can offer you a temporary place to showcase your talent. Rangers and Celtic can also act as the perfect team for high-profile stars who are the wrong side of 30 and want to finish their career at the top. It is because of those reasons that players rarely regret leaving a club like Rangers. Whether they are in the SPL or the Scottish Championship as they are now, they are always going to be considered an option by players who possess plenty of talent without necessarily having the experience or high-calibre performers who have been there and done that. However, in some cases, players have regretted leaving Ibrox for a whole number of reasons, and here we have 10 who wished that they could turn back the clock.
