Given the three I would take Dybala - Bale has ligament and muscle injury problems, those sort of injuries are always made worse by a colder climate so I would expect him to be sidelined for a good part of the season. Ozil it too enigmatic, he plays well when he wants to, not when the occasion demands. Dybala, by contrast, is a strong, young player with a proven record of scoring and assists (even if he has just suffered a hamstring injury) - he is the sort of talent we should be investing in, not RM's cast-offs.
