Michael Flatley should be worried.  Four-year-old Oscar Donnelly has only been Irish dancing for a year, but his set dancing skills would rival any teenager's. In footage sent our way by Chris Nash, we see him make easy work of some really tricky steps, so it's no wonder he is already a four-time champion. Chris told us: "He's won 4 big championships including the All Scotlands (U6 Champ), one in London & one in Dublin & has roughly 18 trophies. "He’s miles too young to enter the World Championships (11+) but he’s definitely one to watch out for!" We couldn't agree more.
