Despite disobeying managerial orders, Hreidarsson is a firm favourite of Curbishley's. Several eyebrows were raised when the Charlton boss chose to sign another defender towards the end of last season but he has proved an invaluable addition to the squad, particularly given injuries to Gary Rowett, Richard Rufus and Luke Young. Hreidarsson is comfortable on the ball for a big man and his height brings an added threat at set-pieces, as demonstrated by his winning goal at Blackburn last month.
