Former Rangers head coach Danny Rohl says "nobody can prepare" for taking over the Ibrox hotseat as he looks back on his time in Glasgow. It's been almost two months since the German head coach left Rangers to join Austrian side RB Salzburg and was replaced by former Hearts head coach Derek McInnes. McInnes has endured a tough start to life in Glasgow and after four games is still yet to lead his new team to a victory.
