Royals defender Adrian Mariappa is targeting a win over Crawley this weekend and believes a cup run can 'breed confidence' throughout the squad.
The centre-back knows all about going far in this competition as he helped Watford reach the FA Cup semi-final in 2006/07 - and sees no reason why the Royals can't achieve a similar feat.
Reading will go into Saturday's cup tie on the back of a 3-1 defeat at Spurs - a game Adrian felt the Royals could have got something out of after a succession of chances with the score at 2-1.
"We had a couple of good chances and had we taken them maybe we could have sneaked a draw, but it's a tough place to come," he recalled.
"They had lots of possession and a lot of shots on goal. But the lads were putting everything into it for each other, throwing themselves in front of everything they threw at us and – with the game still only at 2-1 we could have so easily nicked a draw.
"There's a great spirit here and we're definitely not giving up. The media have written us off, but we were written off before the season started. We're confident we can put together a good few results and we're looking forward to the next game."
That next game for the Royals is this Saturday - and Mapps is relishing Saturday's cup tie as the side prepare to face the Red Devils in Sussex.
"I want to be involved in every game – I have always wanted that since I came into professional football," he said.
"You want to go as far as you can in every competition and its good to get runs in cups, I think it breeds a lot of confidence if you can go through. It'll be a tough game though and we’ll all prepare right mentally for it.
"We know what to expect from the FA Cup. I've been lucky enough to beat teams when I've been the underdog or when we've been the favourites. It doesn't matter – anyone can beat anyone, that's the magic of the FA Cup.
"We're all used to games coming thick and fast. We want to get through to the next round but we'll also use it as preparation for our next league game."
