Bulgaria are struggling in third place in the group ahead of the visit of Montenegro with coach Stanimir Stoilov admitting his side are up against it in their bid to qualify.
“If we win, we’ll keep our chances of qualifying but if we lose, or even if we can’t win, it’s all over for us,” he admitted.
Bulgaria have raised concerns over the state of the pitch at the Vasil Levski national stadium after fans attending a recent Madonna concert damaged the playing surface.
