Current club: Cardiff City
A robust and impressive central defender, who is both strong and quick in the tackle and pacy enough to deal with most forwards he will come up against.
A product of the Tottenham Hotspur Academy, Caulker enhanced his reputation during the 2009-10 season when he spent the full campaign on loan with Yeovil Town, playing regular football and no doubt picking up new found experiences as he featured in all but one of their League One games before picking up a cluster of awards at the end of the season.
The west Londoner made his England debut for the U19s in 2009 and quickly became a regular choice in Noel Blake's squads as they went on to reach the UEFA European U19 Championship Finals in France.
He then enjoyed further loan spells away from Spurs with Bristol City and Swansea City, where his performances in the Premier League during the 2011-12 campaign were particularly impressive.
By now, he was an established international with England Under-21s and challenging for a first-team place with Spurs so it was no surprise when Roy Hodgson called him into the senior squad during 2012.
His senior debut came that November when he started against Sweden in Stockholm and also got himself on the scoresheet.
In the summer of 2013, after featuring for England Under-21s at the Euro Finals in Israel, Caulker left Spurs to join newly-promoted Cardiff City for £8m.
