Mares Bolton deal collapsed over Czech's fitness
Czech Republic defender Pavel Mares failed to win a contract at Bolton because his fitness levels were poor.
Mares looked poised to join the club from Zenit St Petersburg before the transfer deadline and passed a medical, only for the move to break down.
Bolton boss Sam Allardyce said: 'His overall fitness never came close to the level we want our players to attain in our elite testing.
'It would have been too much of a risk to sign him for the amount of money Zenit were looking for him.'
