Munster face a trip to Glasgow tomorrow night for their second game in the Pro 14 campaign.
They opened up with a comprehensive win over the Cheetahs last weekend.
Glasgow Warriors will without doubt provide a much stiffer test for Johann van Graan’s side.
Cahir’s Tommy O’Donnell is now one of the more seasoned campaigners in the Munster camp at 31.
However he admits this still takes him by surprise at times.
