The Robins have suffered back to back 3-0 defeats in league action, but the performances in both were chalk and cheese with an excellent showing against league leaders Bristol City on Tuesday night in front of the live Sky cameras.
'The players have responded really well. We have tried to mix it up a bit this week and the preparation for the game with Swindon has gone well and everyone is now looking forward to the game.
'We know Swindon are missing three first team players and that will present it's own set of challenges for them, but it is not about Swindon Town for me, it is about this group of players and how we can influence the game and impose our our own authority on proceedings.
'We have five games left and we know what is required. The task is simple. The pressure is off externally, the players can play without any fear, the shackles are off and we want them to enjoy their football,' Robertson said.
