Roberts sends Spireites through

Chesterfield made no mistake in their FA Cup second round rematch as they won 1-0 at MK Dons, thanks to Gary Roberts' strike.The Spireites won by the same scoreline at stadium:mk last month, only for the Football Association to order a replay after they fielded Georg Margreitter, who was ineligible for the tie.The man who scored the only goal in the original game, Armand Gnanduillet, had an early header into the bottom corner disallowed for offside.Chesterfield made the decisive breakthrough two minutes before half-time when a long ball by Charlie Raglan ran for Eoin Doyle, who laid the ball off for Roberts to finish past David Martin.Dean Bowditch sent a header from Danny Green's cross wide for the home side shortly after the interval as they sought to ensure their second chance did not pass them by.Gnanduillet missed the chance to seal the tie when he chipped wide with Martin off his line - but the visitors held on to seal a third round trip to Scunthorpe on Tuesday.
