It was to be his only goal of the campaign, making 36 appearances in a season where he was in and out of the first-team due to facing tough competition from fellow central defender Antony Kay. His second year at Tranmere saw Chorley become an integral part of the side, playing in 45 of the 46 league matches, as well as making a further eight appearances in cup competitions.
