Charlton narrowed the gap on the automatic-promotion places to four points after a hard-fought 1-0 victory at Wycombe Wanderers on Tuesday night.
Jason Pearce, who bagged the winning goal at Adams Park on his return to first-team action, believes that the clubs above them may begin to feel the pressure of the Addicks breathing down their necks.
He said: “They'll keep looking behind and see that Charlton keep winning - it will be difficult for them because they know they've got to win. We're four points off it, which at this stage of the season is a decent little gap, but we're just going to keep plugging away and win the games.
“The Manager has said all along that he thinks we can get into the top-two, so he just keeps drilling that into us. At the moment, we're getting the victories, we're getting clean sheets and the boys are playing well. You've got to keep your feet on the ground - if we take our foot off the gas then we'll get beaten by any team in this league. We just need to all stay together.”
1,434 fans made the trip to Buckinghamshire on Tuesday and Pearce realises how crucial their support will be in the final five games as Charlton try and chase down the top-two.
He said: “They've really helped the team and have given us that extra push. I can't thank them enough, it's been great to have them behind us. At the moment ,we're giving them something to cheer about, so hopefully we can keep that going.”
