Rangers face Celtic in only the second Old Firm Derby in the past five years. With Rangers after securing promotion back to the Scottish Premier League next season we'll have plenty of tense clashes between these two sides going forward and today's Scottish Cup semi-final will be the perfect reminder of what we've been missing out on. Celtic's Leigh Griffiths could be the deciding factor between the two sides. Whenever the striker performs to his best, his side invariably tends to win. (Kick Off: 12pm)
