Six Nations: Scotland v Ireland (Sun)

MATCH PREVIEW

One confidence-boosting win, one humbling defeat to bitter enemy England. Scotland and Ireland - often touted as 'Celtic cousins' - have plenty in common as they head into what is likely to be a tournament-defining match for both sides. The similarities don't end there.

Each nation boasts fresh-faced, creative young players that are rich in promise and verve: Stuart Hogg is a real Lions contender after two thrilling tries in two 2013 Six Nations matches, while Ulster duo Luke Marshall and Paddy Jackson make their full debuts for the visitors.
