Paolo Di Canio urged Swindon to keep up the pressure following their 4-1 demolition of npower League Two promotion rivals Southend.
Three first-half goals from Matt Ritchie, Joe Devera and Jonathan Smith put the Robins in control at Roots Hall before substitute Billy Bodin added a fourth early in the second half.
"After we played in the FA Cup on Saturday maybe we were not as fresh as Southend, but we worked hard against a side that have had nine days to prepare to play against us," said Di Canio, who celebrated the win on the pitch with his players at the final whistle.
"This is what it means to me to be a group. They worked hard with the ball, every time they had the chance to go forward they did and we scored four goals. We are now close to the top and to win away from home against a team in Southend's position is amazing.
"Now I learn from the players that they believe more than me in what we are doing. That makes it an easier job for me as the manager. They have the belief and it shows what they can do. No-one expected us to win 4-1 but it shows what we are capable of doing.
"It's now up to them to keep going because they are professionals. They know what they want to do and that makes it easier for me as a manager."
Jean-Paul Kalala's effort that made it 2-1 turned out to be a mere consolation for the Shrimpers as Swindon took second spot to drop the Paul Sturrock's men to third on goal difference.
And Sturrock criticised all of his players for the defeat and urged them to get it right when they travel to his former club Plymouth on Saturday.
"It was the poorest performance I have had since I have been at Southend," Sturrock fumed. "We were sluggish, lethargic and you cannot get away with being like that against a team like Swindon. They have played Tuesday, Saturday and Tuesday but it was hard to see which was the fresh team.
"It was not good enough all over the pitch and the players must now look at themselves in the mirror and stand up and be counted. I will be looking for a reaction at Plymouth on Saturday but it will be another hard game."
