Houllier said: "This is one of the most disappointing spells I have ever had. I just wish we could get all our players back. We are as good as anyone when we have our personnel. We have shown that this season against Arsenal and Manchester United. We must stick to our guns.
"The fans are hurting but no more than more than the players and staff are. We are all disappointed but must remain positive. I am convinced we will have a good spell when everyone is back."
