Speaking to the club's official site, caretaker boss Willie Donachie has admitted that he will not underestimate The Lions' opponents, who must feel they could pull off one of the first shocks of this year's tournament.
"I've been involved with a team that's won the Cup and also been knocked out by a minnow, so I've seen it all.
"Obviously Havant will have nothing to lose", he continued. "So our attitude will need to be spot on. Hard work is vital but I believe the FA Cup has a lot to do with fate.
A lot of teams win the Cup by getting a good run and there are others who might play a great game but lose by the odd goal. That's the beauty of the Cup - everyone's got a chance.
"That's what our opponents will be thinking so we'll have to match their passion and commmitment - that must be our starting point."
