The team us usually under the stewardship of former QPR player Don Givens, but he's currently taking the senior squad on a caretaker basis so Sean McCaffrey will be in charge of the Under-21s.
Joe O'Toole of Watford and Blackburn's Keith Treacy are the other newcomers and Givens said of Chris: "Chris McCann is another midfielder new to the squad. He has been involved with Ireland at other age levels but this is his first call-up to the Under-21 panel. He is a good player and deserves a chance at this level."
Many Clarets have been bemused at his inability to get into this squad previously, but it is a new era for the Republic and he's finally got his place. Best of luck Chris.
