Liverpool will try and keep Emile Heskey at Anfield after Middlesbrough manager Steve McClaren confirmed he was interested in signing the England striker.
Heskey has been linked with moves to Boro and Milan as Liverpool have lined up Auxerre’s Djibril Cisse as a potential replacement this summer.
Boro boss McClaren admitted: “He’s someone we are definitely interested in and we are speaking with Liverpool.”
Meanwhile, Houllier told BBC Sport: “Nobody will be leaving. Surely people know what I think about my players.
“Clearly I must repeat myself. Nobody is going to leave and nobody is going to come in.”
But McClaren responded: “When we’re looking in the January window and we need to score goals, I think there are two types of strikers you can look at and try to buy.
“There’s the 20-goal-a-season man and they’re very, very difficult to find and if anybody’s got them, they hold on to them.
“The other type of striker is someone who can lead the line, who can not just score goals, but also create space and create goals for other people, and I think Emile Heskey falls into that category.
“Everybody has seen at Liverpool how he’s helped Michael Owen, I’ve seen it with England, so that’s what I admire in that player.
“But in the overall picture, taking Emile away from it, they’re the two types of strikers and they’re the types we’re looking for in the window.”
