The Dons won all four of their league games last month, starting with a 1-0 victory at home to Tranmere Rovers.
Di Matteo's side followed that up with a 3-1 win at Hartlepool United and a resounding 3-0 victory at Walsall.
They ended the month with a 3-0 success at home to lowly Hereford United, leaving Di Matteo's men in second place in the table and well-placed to challenge for a second successive promotion.
