Alan made his senior debut at Sheffield United in March 2002, and in spite of further appearances at first team level in 2003/4, injury intervened whenever he seemed to be on the verge of establishing himself.
However, Dunney's patience was finally rewarded during 2004/5 when he became a regular member of the squad and scored his first senior goal in the 2-1 win against Gillingham in October 2005, having successfully switched to a wide midfield role.
Blessed with great pace and energy, Dunney has also slotted into the centre of midfield, only to endure another injury lay off during the 2007/8 campaign.
However that failed to slow him down and he made the right back spot his own last season. Dunney reached 150 appearances during the 2008/9 season and signed a new one-year contract in June 2009.
