Philippe Montanier’s side head to the Madejski Stadium looking for their first away win of the season and Perquis believes they have to toughen up if they are to take all three points away from Berkshire.
He said: "As a team right now we're definitely too nice. We need some more malice and fighting spirit on the pitch to get the ball back quickly and to make sure that we stop conceding easy goals in important times in the game.
"When we concede goals, it isn't just a problem for the back four, it's for the team as a whole and we have to change our spirit on the pitch. Every time we concede a goal, another seems to come straight away and that must stop.
“I’ve heard that we've sold over 1,600 tickets for Reading and the travelling fans deserve a performance from us. We have to show what we can do and we have to show that we can fight like lions when we need to.”
There has been plenty of media talk regarding a proposed takeover of the club but Perquis insists that is not a distraction for the players and that their immediate concern is getting points to take them back up the league table.
He said: “There's a lot of speculation surrounding the club but that happens in football. We can't control it or be affected by it. We're not responsible for anything that happens off the pitch and we know people at the club are working hard to sort things out.
"As a squad we all help each other off the pitch but that hasn't transferred on to the field. We are all good friends when we’re at the training ground or in the dressing room but we need to come together now to put some wins together.
“I firmly believe that good things are just around the corner for this club. We've got very good players here but we need to build some confidence by picking up positive results and that starts at Reading on Saturday."
