"Paul has been back, has been sharp and he has been eager to get out there and put all this behind him," Fedinand told Radio Five Live.
"Sometimes the only place to do that is out on the football field and he's been very happy to be back and out there training and playing again along with the other two boys as well.
"I think Paul will be up for the challenge on Saturday without a shadow of a doubt - probably even more so than he normally would be. He has been a great asset to us this season.
"He has probably got a lot of pent up frustration inside of him and wants to get that out - and the best place to get that out is on the football pitch.
"He has been very important to us - along with the other two boys as well although they probably haven't featured as much as Paul this season."
