The Dutchman will at some point have an operation to address the problem which may force Laudrup into the loan market as he would rather more experience than 18-year old Gregor Zabret to act as back-up to Gerhard Tremmel.
"Let's see. It depends when we can do it (Vorm's surgery),” Laudrup said.
"We have games, and there are times when we have very many games, and times when we have less.
"But we always have games and you can't play with one keeper.
"That's much too risky. If something happens to Gerhard then we would have to play with an 18-year old who is not an experienced goalkeeper.
"That's not good for him or for the team."
