Eric Dier is a rare - if not unique - breed of English footballer.
He is an English youngster who has come through the ranks at the youth system at a foreign club - in this case Sporting CP's.
A highly-rated youngster, Dier made his debut for Sporting's under-19 side aged only 16 and was quickly linked with a move to one of the big English clubs.
Since coming back to Sporting in 2010, Dier has progressed steadily, making regular first-team appearances as well as working his way through the England youth ranks.
A young English centre-back with a continental education will tempt many Premier League sides.
