The Cottagers rose from the foot of the table and to within five points of safety on Saturday thanks to a late header from Hugo Rodallega that gave them a vital 2-1 victory.
Next up for the Cottagers are 17th placed Norwich, who will enter the tie having just sacked Chris Hughton.
To make matter worse for the Canaries, they will then face Liverpool, Manchester United, Chelsea and Arsenal in their last four games, which could see them dragged into the bottom three.
Sidwell – who has been an ever present for Fulham this term – believes that his side can push on from their weekend victory and complete what looked a few weeks ago to be an impossible comeback:
“There is [light at the end of the tunnel],” he told talkSPORT.
“We said before the Aston Villa game, if we can get a win there and get the ball rolling then we’ve got a great chance [of staying up].
“The fixtures that we’ve got to come, especially the home games for us against Norwich, Hull and Crystal Palace, mean we’ve got a chance to get points.”
Sidwell then went on to describe Felix Magath – their third manager of the season – as a “hard” boss:
“To describe him, he’s hard but fair,
“When you come into work he wants everything done with 110% [effort], whether it’s stretching, passing the ball or going into a game and doing tactics.
“In that respect a few of the boys who have had him before over in Germany have said this is nothing compared to what he can do.”
