The Jamaican international says the Potters does not fear the Champions League winners.
“At this club the lads work really hard and we are not afraid to lose,” Fuller told Sky Sports News. “When teams play like this they have nothing to lose.
“At the beginning of the season nobody expected us to do well against Arsenal, to do well against Liverpool, but we did have some positive results against them and hopefully we will do the same on Saturday against Manchester United.
“The confidence is brimming at the moment. We haven’t lost in four games in the cup as well, so I mean it is going well and as I said before we are not afraid to lose so hopefully we can go up there and give it our best and hopefully our best will be good enough.”
