League Two leaders Chesterfield maintained their strong start to the season with a 1-0 home win over bottom side Accrington Stanley.

Hartlepool United remain winless this season after a 2-1 home defeat at the hands of Wycombe Wanderers.
Substitue Max Kretzschmar scored both Wycombe goals in the 51st and 69th minutes, with James Poole's stoppage-time strike proving in vain for Hartlepool, who remain in the bottom two.
