Midfielder Callum Reilly disappointed that City couldn't capitalise on last week's three points...
Nicky Ajose registers his first two goals in Swindon colours this season, scoring twice at the Ricoh, with a further goal from striker Jonathan Obika.
George Thomas netted a consolation for City in stoppage time, but ultimately the Sky Blues were left empty handed - another dent in their quest for League One survival.
Callum Reilly commented: “It was disappointing, and we’ve had a positive week after the last result so it was unexpected. Its upsetting because we weren’t able to transfer that positivity on to the pitch today.
“We were well in the game, it is all about the first goal in this league, and unfortunately it fell to them. In those situations you need to stay in the game but their second has killed us off.
“We kept going, but inevitably it was two goals too many in the end. We haven’t been aggressive enough in either boxes, or reacted well enough - to score a goal or prevent a goal.”
City now turn their attention to Bury on Tuesday evening, eleven points adrift of safety, with 13 league games left of the campaign.
Reilly added: “The pitch isn’t conducive to a passing game, we had a go, but the first-half just wasn’t good enough.
“We keep going, and we keep fighting, we have a never say die attitude. We go to Bury on Tuesday night, it is a setback today, but we have to move on. Don’t dwell on a bad result.
“As a group we have to keep believing, there are things we have to work on no doubt.”
