The former Valencia coach conceded Liverpool's title hopes were as good as over for another year, but underlined his determination to salvage a trophy from a season that is threatening to fall apart.
He said: "You have to be realistic and say that winning the League will be difficult. I don't want people to lose hope completely, but the two teams at the top are both very good and have a lot of points.
"We have to try to win every game, but it is clear the FA Cup and Champions League are very important to us. I will not leave anything to chance against Havant & Waterlooville.
"I have a lot of confidence in the squad, but you never know what might happen in football. With that in mind, Gerrard, Torres and Carra will all be involved.
"They will be on the bench at least, because I intend preparing for this tie as if it were a Champions League or Premier League game.
"We have already done that by watching them a couple of times and studying DVDs and that level of professionalism must be maintained right up to the final whistle.
"I have never known a gap of five divisions before but I am wary of what can happen in games like this.
"I know what it would mean if we lost - it would be one of the biggest shocks of all time. It is nice for football for a team like this to come and play at Anfield, but that is as far as I want it to go.
"Everyone will expect us to win and score a hatful of goals, but it is not as easy as that. We have a lot of work to do and we will treat them with the utmost respect."
