The Reds have just ten league games left in 2009/10 and Lee is looking for a good run of form so the season can end on a high note with Champions League qualification.
"There is a massive hunger. The boys are very determined, professional and focused. We want to get as high as we can [in the table]. We never prepare for failure at this football club," said the assistant manager.
"It has been an irregular season for us and that concerns me more than any other team's results because I'm not involved with any other team, but we're just going to try and get the best out of each and every game.
"We are working very hard and tirelessly, as are all the players, to try and make sure we keep this momentum going. I think results have proven that.
"There have been certain disappointments along the way [this season], and we know we're not firing on all cylinders, but it's a case of getting some momentum going and we believe we have.
"If everything clicks into place, then who knows? There's still a lot of football left to be played this season. We'll keep battling and the boys are showing great focus."
