Manchester City defender Vincent Kompany asn't figured much this season for City due to a recurring calf problem.
The Belgian is almost match fit but boss Manuel Pellegrini has fears the injury will return.
"It's impossible to know but he's [Kompany] working without any problems, without fear, so it would be bad luck if he has another injury.
"It's very difficult to find a particular thing about a muscle injury. There's a lot of things you can do to try to have less injuries but no one will be sure you are not going to have any more."
