Jimmy Dunne (D QPR b.1997)
Surprised that Dunne hadn't a thread of his own, considering he has a full season of senior football under his belt. Anyway, he made his debut for Scottish Premiership table-toppers Hearts in their victory over Kilmarnock and even had a shot on goal saved: http://www.heartsfc.co.uk/news/6926
While it looked for a little while that there was a chance he might break into the Burnley first-team squad, this is still a big step forward in his career. If he can consolidate his position over the next few weeks he surely moves him up a level in terms of the pecking order for National Team centre-backs, from a group of youngsters with potential (Masterson, Nolan, O'Connor, O'Driscoll, Collins) to our second-tier/fringe group (along with Egan, Keogh and Hoban... maybe Williams if we're using a back three). Top tier options would be Clark, Rice, Long and Duffy.
