Milan - Juventus have been dealt a blow ahead of their Champions League clash at Bayern Munich on Wednesday with key players Paulo Dybala and Claudio Marchisio both ruled out with injury.
Argentina striker Dybala, who scored in the first leg when Juventus fought back from 2-0 down to seal a 2-2 draw in Turin, injured his calf in training on Monday while Italy midfielder Marchisio has torn a calf muscle.
