Nugent is No 2 at Leyton Orient having been in a similar position at Swansea City as well as playing for the club and a (very) short spell as caretaker manager before the appointment of Roberto Martinez.
And he believes that the O’s have a chance of upsetting the Swans in the same way that they upset our promotion rivals Norwich in Round Three.
Nugent told the Western Mail โWe know weโre playing one of the best teams in the Championship on Saturday
โAnd it goes without saying that itโs a very tough game for us.
โBut we had a tough game in the last round against Norwich – a similar side to Swansea in the way they play โ and had a very difficult game, but we played very well and deserved to get the win.
โIโm sure there are Swansea supporters that fancy their chances of being in the fifth round come Sunday, just as Iโd expect our supporters to think like that if we drew a team from the league below at home.
โBut weโre looking for a result and we can take confidence from the last round we can do that.
โItโs a big ask for us but thatโs what weโll be looking to do,โ said Nugent, who also spent time in South Wales in Cardiff City colours before his Swans stint.
โAnd Iโm sure Brendan Rodgers will not be taking the game lightly; he will have watched us a few times already and got his preparation spot on because he will want to make sure Swansea are in the next round.
โBut itโs 11 players against 11 and ours have seen that it can be possible to go and get a result against good sides now.
โOver a period of a season thereโs a big difference between ourselves and Swansea City โ but in a one-off game you can have that extra spring in your step.
โWhat Swansea have done is fantastic and great credit to everyone involved,โ said the 41-year-old.
โIโve got some great memories from my time there; I left Orient as a player when they signed me and the club were something like six points adrift when I joined.
โWe had that brilliant day against Hull to stay up and things have just gone on and on from there.
โBut it hasnโt surprised me โ even just after we avoided going down you could see the club was looking to the future with the new stadium and the players like Alan Tate and Leon Britton that came in.
โTheyโve gone about it the right way on and off-the-field, progressing gradually and the chairman has done a great job running the club.
โItโs a great example for others to follow and Iโm sure there can be more success for the club to come.โ
