Celtic boss Neil Lennon wants another look at keeper Stipe Pletikosa after a quiet trial match against Cardiff.
Lennon said: "The keeper didn't have a lot to do and it would be difficult to sign him on the evidence of that but be will have another look. A short-term contract is a possibility.
"I want another goalkeeper - we've only got two at the moment. In any scenario I want to bring another goalkeeper in."
