Career
A winger, he joined Icelandic club Fram in 2008. Tillen began his career with Chelsea, and played for their academy and reserve teams before joining League Two club MK Dons on a free transfer at the end of the 2005-2006 season. Manager Martin Allen described him as "an attacking left sided player with good pace".
He made his debut in the League Cup, and came on as an 84th-minute substitute in the 2–1 league defeat at home to Chester City on 23 September 2006.
Tillen then spent a month on loan to Thurrock of the Conference South, where he made two league appearances, before his contract with MK Dons was terminated in January 2007. He took time out of football before signing for Southern League club Thatcham Town, managed by his father, in December 2007.
