Hibernian manager Pat Fenlon hopes his new signings will help add the physical and mental strength needed to turn the tide in the Edinburgh derby.
Hibs host Hearts in the Clydesdale Bank Premier League aiming to end an 11-game run without victory in the fixture and avenge May's 5-1 William Hill Scottish Cup final defeat.
Former Hearts defender Alan Maybury and former Coventry midfielder Gary Deegan could make their debuts, and Fenlon hopes they can help instil a more solid approach from his team.
Fenlon said: "In some of the games we have probably been bullied a little bit and we have got to make sure we are strong.
"We could probably do with a couple of more to strengthen the squad. The two boys who have come in have plenty of experience and they will relish playing on Sunday. I don't think either of them will fear going out there on Sunday, that's for sure.
"Alan has great experience and Gary has that and a bit of steel about him. He will relish Sunday and that kicks in to other players."
Hibs are under pressure to give supporters some form of lift after a long summer in the wake of their Hampden thrashing by Hearts.
Their first attempt to do so ended in failure as they lost 3-0 to Dundee United last weekend. Another defeat to Hearts could risk undermining Fenlon's summer rebuilding job but the Irishman has demanded his players rise above the fear factor.
"They have got to enjoy playing," the former Bohemians manager said.
"I've said that to them this week, if they can't enjoy playing in this atmosphere and on this surface.. They should be feeding off that. They have to get the supporters behind them and have a right crack at them."
